Answer 1

u = tanx

can you go from here?

forty-four centimeters

please help me

Answer 3

As sourwing has stated...if you do a simple u-sub making u = tan(x)...the derivative of tan(x) = ?

Answer 4

Yeah I got the far, my final answer is e^tanx+c but I'm not sure if it's right

Answer 5

That is correct! @TheAni-Trix

Answer 6

\[\large \int\limits^{}_{}e^udu = e^u + c = e^{\tan(x)} + c\]

Answer 7

Oh okay thank you. ^- ^

Answer 8
