If tan theta = cot theta then value of( tan theta + cot theta)square is

Answer»

Step-by-step EXPLANATION:

Given:  \: tan \theta \:  = cot \theta \\ therefore \\  {(tan \theta \:   + cot \theta )}^{2}  \\  = {(tan \theta \:   + tan \theta )}^{2}  \\  = {(2tan \theta )}^{2} \\  = 4 {tan}^{2}  \theta
