Question

need help on an integration problem

Answer 1

\[\int\limits_{0}^{\pi/4}\tan^2xdx\]

Answer 2

not sure how to do this by hand

Answer 3

Hint: Think of an identity for (tan x)^2. Substitute for (tan x)^2.

Answer 4

ok thanks

Answer 5

sec^x-1

Answer 6

thanks, got it know

Answer 7

Great! Now substitute (sec x)^2 - 1 for (tan x)^2. I'd strongly suggest that you enclose (sec x)^2 - 1 inside parentheses.

Answer 8

Good...you've been able to solve the problem on your own? Fantastic!

Answer 9

yes 1- (pi/4) thanks, I was not thinking about that method. Too busy thinking about u du method and using an integration formula......

Answer 10

sorry forgot to write (sec(x))^2 -1 typing too fast on my part

Answer 11

thanks again

Answer 12

My great pleasure. Keep up the good work! :) MM
