Question

e^integral(tanx)dx

Answer 1

Integration by parts

Answer 2

u = tanx
du = ?

dv = 1
v =

then uv - integral {vdu}

Answer 3

once you complete the integration, raise e to the integral solution

Answer 4

mhm I know that but in a solution that someone sent me, they have something like e^integral (tanx) = e^lnsecx = secx and I don't really understand how they got the e^lnsecx. Can you explain that by chance?

Answer 6

Didn't have what I was looking for but thank you! :)

Answer 7

whenever i see tan(x), i usually solve it by using integration by parts

Answer 8

okay but it's how the integral of it is in the power of the e constant, it's a bit confusing

Answer 9

e is outside of the integral, so you don't need to worry much about it,
you just integrate the tan(x), and put the integrated solution as an exponent to e

Answer 10

Okay thank you so much!
