Reflection of Video

Video 1
this video teaches us how to see of the object from a different way. From this different way we can see the other thing of this object. So we can see all of things which are have of this object.

The meaning of this video are:
1. he convinces everyone to convince themselves that they can
2. he invites everyone to believe themselves that what they believe is true
3. he tries to teach everyone to believe in other people
besides that, to explore the faith in other people, we need self actualization. So make them to believe us with our self actualization.

in the song that is on this video include matters related to mathematics. so many materials in mathematics like multiple, trigonometry, exponent, grade, etc.

how to solving differensial
we will find the integral of this equation:
dy/dx=4x2

next,trying to get dependent variable y, all of itself
so the steps are:
integral the equation
∫dy=∫4x2 dx
so, y=4/3 x3 + c

video 5
to solving the equation in the form of general, we can addition the same number in each segment. So it make equality.
Example:
x-5=3
to solve that,we addition number 5 in each segment.
x-5+5=3=5
so in left segment remaining variable x
x=8

A log Bx=C
Xb=ac
CxlogA=AB (xb)c=Xbc
Log xAc=bc
C x log A=x log Ac
C log xA=logxAc
X log A+xlog B=xlog(AB)
Xlog A=n xn=A
XlogB=m xm=B
Xlog(A/B)=L xL=A/B=xn/xm=A/B
Xn-m=XL
