reteL the viDeo abouT mathematic in my wordS

1. Do you believe me?
The first video tells me about “Do you believe me? This video contains about a speech by a child. This child is a boy, he is 10 years old. In this speech he was speaking about believing. In many times he let fly a question. This question is Do you believe me. Actually I don’t understand what he said, but what he said has an essence that in our life we always need each other.From that video, I think that we have to believe with our ability.

2. What you know about math?
The second video tells me about” The materials which is discussing in mathematics”, there are:
o Significant figure
o Limit
o Exponent
o Trigonometry
o Integral
o Matrix
o Differential
o π

3. English Solving Problem
The third video tells me about one example of mathematics problem. In this video shows the graph of y=g(x), if the function h is defined by f(x) equals x plus one ( f(x) = x + 1) If 2 times f(p) equals twenty ( 2f(p) = 20 ) . What is the value of f(3p)? this is one example of mathematics solving problem.

4. properties of Logarithms
The fourth video tells me about properties of Logarithms, there are :
a. Log x to the base b equals y symmetry with b power y equal x

b. Log x to the base 10 equals Log x

c. Log x to the base natural numeral equasl Ln x (this natural logarithm)
example:Log 100 to the base 10 equals x.What is the value of x?
answer :Log 100 to the base 10 equals x, become 10 to the power of x equals 100, so x equal 2.

5. The graph of rational function.
The fifth video tells me about the graph of rational function.

6. Trigonometry
the sixth video tells me about trigonometry. this video tells about sinus, cosinus and tangent. we can get the value of sinus with formula opposite over hypotenuse (soh). we can get the value of cosinus with formula adjust over hypotenuse (cah). we can get the value of tangent with formula opposite over adjust (toa).
