Ok. I think I did it.... But calculation is tedious... Is there any shorter approach? @Naman
Any good source to learn Feynman trick?
It's simple. Expand sin(x+@)... Then take out sin^4x... Put cotx=z
it is a question of RD sharma
I thought it was infinity written there
x=tan@ then convert to f(a+b-x) , add both, bam ! Done
Maybe also possible by feynman trick
How to do this through Feynman trick?
Oh my school teacher gave this Question,
I was only able to solve this
@Gajraj_Singh Is the answer integer type?
Coz i am getting weird answer. Smthng smthng in roots.
Ohh just 1 digit chngeee
Got it @Gajraj_Singh mistake
Im feeling sleepy somewhere took 2 to 3 and solved fully. And just saw i wrote it wrong.
Btw nice question.
Please send solution bro.
Will send tomorrow morning i just did very roughly. Plus am feeling very sleepy. Will ttach neat tomorrow.
