find the general solution of tanx + cotx = 2cosecx
I hope, this answers helps you finally....
tan(x) + cot(x) = 2 cosec(x)
⇒ [ sin(x) / cos(x) ] + [ cos(x) / sin(x) ] = 2 cosec(x)
⇒ { sin^2(x) + cos^2(x) } / sin(x) cos(x) = 2 cosec(x)
⇒ 1/sin(x) cos(x) = 2 cosec(x)
⇒ 1 / sin(x) cos(x) = 2 / sin(x)
⇒ sin(x) cos(x) = sin(x) / 2
⇒ cos(x) = 1/2
⇒ cos(x) = cos(pi/3)
⇒x = 2n(pi) +/- (pi/3),where n ∈ Z
Hence, the general solution is given byx = 2n(pi) +/- (pi/3), where n ∈ Z.
