Question

Evaluate the Integral: (x^2tanx)/(1 + cos^4x) dx [-pi/4, pi/4]

Answer 1

is 2tanx the exponent?

Answer 2

no 2 is

Answer 3

For everyone else:\[\large\int_{-\frac{\pi}{4}}^{\frac{\pi}{4}}\frac{x^2\tan x}{1+\cos^4x}dx\]

Answer 4

thanks that's exactly my question

Answer 5

Is it an odd or even function?

Answer 6

When a function is odd, \[
\int_{-a}^a f(x)dx = 0
\]

Answer 7

yeah your right... that would make sense, it is an odd function... thank u :)
