Re: integrate

Hi!


I guess you need the steps, but I cannot figure them out now smile

Sometimes, the result can give some clue, even though it's not the case for me now. Anyway, Mathematica says:


That's a weird result, though! Hope you get luckier than me smile

Re: integrate

Hi mathkeep;

Can I ask what textbook this came out of ?


In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
Always satisfy the Prime Directive of getting the right answer above all else.

Re: integrate

hi Ricky!
heyee..i have got the solution for the integral..


but the hint u provided isnt working for the integral

i converted the above expression into the form..
...
n then i applied the form

after then i put tan(x)=t
n then putting all values..ultimately gave me

after that m confused what to do next..
