What?
rishavraj (rishavraj):
rishavraj (rishavraj):
I solved the question...just assuring answer is correct or not
OpenStudy (vishweshshrimali5):
Your solution ?
rishavraj (rishavraj):
\[\sqrt{3}[\ln (t-\sqrt{3})/(t+\sqrt{3})] + 2\tan ^{-1}(t) + C\]

And t is ?
rishavraj (rishavraj):
\[t = \sqrt{(2-sinx)/(2+sinx)}\]
OpenStudy (anteater):
Could always check by taking the derivative of the answer. :)
OpenStudy (vishweshshrimali5):
Yeah @anteater is right,
OpenStudy (anteater):
I'm lazy ... I'd use the calculator to check. ;)

Just a minute I am checking it
OpenStudy (vishweshshrimali5):
I am getting that the answer is wrong.Let me recheck my own answer.
OpenStudy (vishweshshrimali5):
Was it \(\ln (t-\sqrt{3})/(t+\sqrt{3})\) or \(\ln [(t-\sqrt{3})/(t+\sqrt{3})]\) ?
OpenStudy (anteater):
I haven't tried to solve it. Above, you wrote ln(t−3√)/(t+3√)
OpenStudy (vishweshshrimali5):
I want to know that is it whole natural log or log of (t−√3) and then finally divided by (t+√3) ?

Actually, I shouldn't have tried to answer your question, as it was for rishavraj. :) He will know what he meant by his notation.
rishavraj (rishavraj):
\[its \ln [(t-\sqrt{3})/(t+\sqrt{3})]\]
OpenStudy (vishweshshrimali5):
Ohh then wait one more minute pls.
rishavraj (rishavraj):
not to bother about it anymore i am damn sure now that its correct
OpenStudy (vishweshshrimali5):
okay
