Endri Substitute cot(2x) by cosx/sinx and cosec2x by 1/sin2x and do some work to get a quadratic then solve it it is easy. good luck

Hello, endri! We have: . . . . . . . . . . . . . . . . . . . Then: .
I strongly believe that we should guide the readers to do some work by themselves and study more rather than solve them their homework. MINOAS
THANK YOU VERY MUCH MAN
cosec^2(x)=1+cot^2(x),,and i wasnt sure if it was right to say that cosec^2(2x)=1+cot^2(2x)... thanks again man
minoanaman thanks for your help too man.. i had solved this equation,but i was not sure if the method that soroban showed me was right
