Let us remind ourselves that the integral we are trying to solve is; For most integrals of products and powers of tanx tan x and secx sec x, we rewrite the expression we wish to integrate as the sum or difference of integrals of the form ∫ tanjxsec2xdx ∫ tan j x sec 2 x d x or ∫ secjxtanxdx ∫ sec j x tan x d x. This just cancels in the end to 0 = 0.

3) secx + tan x+ c. 4) log sin x + log cos x + c. Let u= sec ( x) 2.use integration by parts now doing the first way results in the integrand looking like ∫ u 3 d u = 1 4 sec 4 ( x) + c which is correct but it's not the answer i'm looking for, so instead we'll do it the second way.
We can do the integration of secant x in multiple methods such as: The first one is simple, but what is the integral of. 2) log (1 + sec x) + c.
Sec x = sec x * [ (sec x + tan x) / (sec x + tan x)] = g(x) ln (sec x + tan x) = integral of g(x)dx so, let u = ln (sec x + tan x) du = sec x * [sec x + tan x] / [sec x + tan x] dx integrating u du = u^2/2 = [ln (sec x + tan x)]^2 / 2 + c ∫ sec x tan x d x = sec x + c. So simply divide by 3 to get your answer:
