Homework Statement
Evaluate. This may not require integration by parts:
integral of x^5 sec(x^6) dx
Homework Equations
integral sec x dx = ln | sec x + tan x| + C
integral u dv = uv - integral v du
... tabular integration process
The Attempt at a Solution
u = sec x^6
du = ln | sec x^6 + tan x^6 | + C
v = 1/6x^6
dv = x^5
secx^6 * 1/6x^6 - integral 1/6x^6 * ln |sec x^6 + tan x^6 |
(secx^6)/6 * x^6 - integral (x^6 ln | sec x^6 + tan x^6 | + C)/6
... this just looks really wrong. Help! :)
