Question

Integration with a trigonometric function

Answer 1

what is the question ?

Answer 2

\[\int\limits_{0}^{pi/4}(\tan^2x)dt = \]

Answer 3

tan^2?

Answer 4

You have to wait for it to convert to the equation style... its tangent squared x

Answer 5

does it say how it wants to solve it?

Answer 6

I'm assuming by integrating and using F(b) - F(a) but I don't know how to use the chain rule with integration

Answer 7

alright you ned to use an identity \[Cos^2x + Sin^2x = 1\]
deriving from that yuo get \[1+Tan^2x=Sec^2x\]

Answer 8

does this help?

Answer 9

solve for tan^2x and then you'll get something that you can integrate

Answer 10

got it
