How to solve the integral of y=1/(x-2)^1/3?

We'll use substitution technique to solve the
integral.


We'll put x - 2 =
t.


We'll differentiate both
sides:


dx = dt


We'll re-write
the integral in t:


Int dx/(x-2)^1/3 = Int
dt/t^1/3


We'll use the negative power
rule:


1/t^1/3 = t^(-1/3)


Int
dt/t^1/3 = Int t^(-1/3)dt


Int t^(-1/3)dt = t^(-1/3 +
1)/(-1/3 + 1) + C


Int t^(-1/3)dt = t^(2/3)/(2/3) +
C


Int dx/(x-2)^1/3 = [3(x-2)^(2/3)]/2 +
C

Calculate tan(x-y), if sin x=1/2 and sin y=1/3. 0

We'll write the formula of the tangent of difference of 2 angles. tan (x-y) = (tan x - tan y)/(1 + tan x*tan y) ...
