Question

∫(sec θ tan θ)/√(e^(sec θ))

Answer 1

derivative of secx = tanxsecx
helps ?

Answer 2

let
t=sec(theta)

dt=sec(theta)tan(theta)*d(theta)

Answer 3

just as sami said :)

Answer 4

using this makes the integral simple

Answer 5

\[\theta=\sec(\theta)\]
\[\Large dt=\sec(\theta)\tan(\theta)d \theta\]
integral becomes
\[\Large \int\limits \frac{1}{\sqrt{e^t}} dt\]
can you solve this ?

Answer 6

Re-writing the integral @sami-21 wrote using rational exponents we get:\[\bf \large \int\limits_{}^{}e^{-\frac{t}{2}} \ dt =?\]This should certainly make things a bit easier ;P Can you solve this? @Julie-Ann

Answer 7

yup:)
I should have written in that format :P

Answer 8

@sami-21 I think he gave up after looking at the way you wrote it lol...I almost gave him hope but seems as if he has left?

Answer 9

i guess he/ she is looking for the answer ;)
