What you know about math ?

This video is about the song which descript mathematic, I think it’s one of alternatives to attract people to study mathematics. In mathematic we can not apart from the symbol of mathematic, for the example is aritmathic operation symbol. This symbol is plus, minus, multiplied, and divided. In mathematic we also meet a significant figure. And then a kinds of number. The tool which familiarly with mathematic is calculator. Calculator can help us to solve the problem of mathematic. A kinds of study object which learned in mathematic, they are trigonometry, exponents, algebra, geometry etc. Mathematic is a mystery which make us burned up to solve.
Mathematics is not only about numbers, it is also contains sketched graph and symbols. For example sinus graph, phi (п), greater than (>), and so on. In the equation, there are arithmetic operations such as addition, subtraction, multiplication, and division.

ENGLISH SOLVING PROBLEM

1. Let the function f be defined by f ( x ) equals x plus one , if 2 f ( p ) equals 20, what is the value or f ( 3p ) ?
Answer:
f (x) equals x plus one and 2f(p) equals 20
→ f(3p) equals ………….
F(x) equals x plus one
→ 2 f(p) equals 20
F(p) equals 10 → f(p) equals p plus one equals 10
→ p equals 9
So, f(3p) equals f(27) equals twenty seven plus one equals twenty eight.

2. In the x y coordinate plane, the graph of x equals y square minus four intersects line l at (zero, p) and (five, t). what is the value of p and t? and then find the line equation.
Answer:
Gradient equals m.
We know the equation x equals y square minus four.
Line l equals m equals y two minus y one in bracket over x two minus x one in bracket.
We have known that the intersects (zero, p) and (five, t). so, m equals t minus p in bracket over five. Substitute the coordinate in equation.
x equals y square minus four.
Equivalent zero equals p square minus four.
Equivalent p square equals four.
p equals two or negative two.
According to the graph, the value which serve turn is negative two.
x equals y square minus four.
Equivalent five equals t square minus four.
Equivalent t square equals nine.
t equals three or negative three.
According to the graph, the value which serve turn is three.
So, the value of p is negative two and t equals three.
Gradient equals t minus p in bracket over five.
Gradient equals three minus negative two in bracket over five.
Gradient equals five over five.
Gradient equals one.
The line equation:
y minus three equals one open bracket x minus zero close bracket.
y minus three equals x minus zero.
y equals x minus zero plus three.
So, the line equation is y equals x plus three.

PROPERTIES OF LOGARITHMS

Logarithm x with base number b equals y.
Equivalent b to the power of y equals x.
Notation: Logarithm x with base number ten equals Logarithm x, so Logarithm x with base number e equals natural Logarithm x.

Remember of Exponent function :

A to the power of m times a to the power of n equals a to the power of m plus n in bracket.
A to the power of m over a to the power of n equals a to the power of m minus n in bracket.

So, logarithm “b” with a base number “a” equals n →b equals a to the power of n. logarithm “a” with a base number “g” equals x →a equals g to the power of x. logarithm “b” with a bare number “g” equals y →b equals g to the power of g. What do you now, logarithm “a” times in bracket ?

Answer :
To assumed :
Logarithm “a” with a base number “g” equals x→a equals g to the power of x.
Logarithm “b” with base number “g” equals y→b equals g to the power of g.

↔ A times b equals g to the power of x times g to the power of y

↔ A times b equals g to the power of x plus y in bracket.

↔ Logarithm “a” times “b” in bracket with a base number “g” equals logarithm “g” to the power of x plus y in bracket with a base number “g”. So, logarithm g to the power of x plus y in bracket with a base number “g” equals x plus y in bracket times logarithm “g” with a base number g equals x plus y.

↔ So, logarithm “a” times “b” in bracket with a base number “g” equals logarithm “a” with a base number “g” plus logarithm “b” with a base number “g”.

↔ A over b equals g to the power of x over g to the power of y. A over b equals g to the power x minus y in bracket. Logarithm a over b in bracket with a base number “g”. Logarithm a over b in bracket with a base number “g” equals x minus y in bracket times logarithm g with a base number “g”. Logarithm a over b in bracket with a base number “g” equals x minus y. So, logarithm a over b in bracket with a base number “g” minus equals logarithm a with base number “g” minus logarithm b with a base number “g’.
Example:
1. Logarithm twenty five with base number five is……..
Answer : Logarithm twenty five with base number five equals logarithm five to the power of two with base number five equals two times logarithm five with base number five equals two.

Pre Calculus

Graph of rational function
- can have discontinuities
- has a polynomial in the denominator.
Look at the sample:
f(x) equals x plus two in bracket over x minus one in bracket.
When x equals one, this function become :
f(one) equals one plus two in bracket over one equals one minus one.
Equals three over zero.
The denominator is zero, this is a bad choice.
Insert zero, when x equals zero, so the value of y is negative two.
Insert one, when x equals one, so the value of y is zero. It is break in function graph.
So, if the function sketch in graph it is discontinuity, because it is break when x equals zero.

Rational function don’t always work this way. Not all rational functions will give zero in denominator. For the example f(x) equals one over open bracket x plus one close bracket. This function is never zero.

ENGLISH TRIGONOMETRY

Trigonometry is a branch of mathematics that discuss about the angle on each quadrant. Where trigonometry also related to the triangular carpenter's square. Which is used to find the value of sine, cosine, tangen, cosekan, cekan, and cotangen.Where the sinus is opposite over hypotenus.
cossinus equals adjustion over hypotenuse.
Tangent equals opposite over adjustion.

I. The Nature of Logarithm.

Remember of Exponent function :

A to the power of m times a to the power of n equals a to the power of m plus n in bracket.
A to the power of m over a to the power of n equals a to the power of m minus n in bracket.

So, logarithm “b” with a base number “a” equals n →b equals a to the power of n. logarithm “a” with a base number “g” equals x →a equals g to the power of x. logarithm “b” with a bare number “g” equals y →b equals g to the power of g. What do you now, logarithm “a” times in bracket ?

Answer :
To assumed :
Logarithm “a” with a base number “g” equals x→a equals g to the power of x.
Logarithm “b” with base number “g” equals y→b equals g to the power of g.

↔ A times b equals g to the power of x times g to the power of y

↔ A times b equals g to the power of x plus y in bracket.

↔ Logarithm “a” times “b” in bracket with a base number “g” equals logarithm “g” to the power of x plus y in bracket with a base numbet “g”. So, logarithm g to the power of x plus y in bracket with a base number “g” equals x plus y in bracket times logarithm “g” with a base number g equals x plus y.

↔ So, logarithm “a” times “b” in bracket with a base number “g” equals logarithm “a” with a base number “g” plus loagrithm “b” with a base number “g”.

↔ A over b equals g to the power of x over g to the power of y. A over b equals g to the power x minus y in bracket. Logarithm a over b in bracket with a base number “g”. Logarithm a over b in bracket with a base number “g” equals x minus y in bracket times logarithm g with a base number “g”. Logarithm a over b in bracket with a base number “g” equals x minus y. So, logarithm a over b in bracket with a base number “g” minus equals logarithm with a base number “g” minus logarithm b with a base number “g’.

II. abc Formula

We know that square equations of universal is “a” times x square plus “b” times x plus “c” equals zero. And then, if we want to difference square equation of universal.
With all over coeffisien with “a” and then we will piocure x square plus “b’ over “a” times x plus “c’ over “a” equals zero. And then we are plus to second internade with “b” square over open bracket four times “a” square close bracket. So be can equation is x square plus “b” over “a” square plus “b” square over open bracket four times “a” square close bracket equals “b” square over open bracket four times “a” square close bracket. We will a group to x plus open bracket two “a” close bracket equals b square over four “a” square minus c over a equals b square minus four times “a” times “c’ in bracket all over four times a square in bracket. So, be can x plus “b” over open bracket two times “a” close bracket equals plus minus “b” square minus four times “a” times in bracket all over open bracket four times “a” square in bracket square root. So, we will x equals minus b plus minus open bracket “b” square minus four times “a” times “c” in bracket square root close bracket all over open bracket two times “a”. So, we can abc formula is x equals minus “b” plus minus open bracket “b” square minus four times “a” times “c” in bracket square root close bracket all over open bracket two times a close bracket.

A circle measurement methode has introduced by people in Egypt since 2450 SM with interralate triangle. In papyrus moskow and rhind can found task of geometry. Where, area of circle sawed equals eight over nine time diameters and then volume of cylinders right equals area of base times height. So, we can apart is area of circle equals eight over nine times diameters in bracket square. We know that diameters equals two times radius, and then can found the ares of circle equals eight over nine times two times radius in bracket square equals sixty four over eighty one times four times radius square equals two hundred fivety six over eighty one times radius square equals three point one six times radius square. So, people in Egypt has found phy number is three point one six. And then phy analytic wisthel that phy equals three point one four.

IV. Two square is irrational number.

Prove that two square is irrational number is we can a issoscaller right triangle with right side is one. So, we can determine apotema is one square plus one square in bracket square root equals two square root. We represent two square root is rational number the meaning of two square number equals “a” over “b”, where “a” and “b” is a integer prime then two square root equals “a” over “b”. “a” equals b times two square root or “a” square equals two times “b” square. Because “a” square equals two times a integer then “a” square of even integer. Prove “a” equals two times “c” then equations to: four times “c” square equals two times “b” square two times “c” square equals “b” square. So, that is prove of two square root is a irrational number.

V. Fine Intersection of y equals x square minus one and x square plus y square equals theerty.

We difference equations of x square plus y square equals theerty →y square equals theerty minus x square.
y equals plus minus open brecket theerty minus x square close bracket square root. We take y equals plus open bracket theerty minus x square close bracket square root because y equals x square minus one in first ans second quadrant.
We make x square minus one equals open bracket theerty minus x square close bracket square root. We square in second space. Then x to the power of four minus two times x square plus one equals theerty minus x square. x to the power of four minus three minus x square minus twenty nine equals zero.
