Question

prove that , tan A / (1 + tan² A )² + cot A / (1 + cot² A )² = sin A cos A ​

Answer 1

Answer:

Important formulas: (1) Sin^2 A + cos^2 A = 1 (2) cot A = cos A/sin A (3) 1/sin ^2 A = cosec^2 A (4) 1/Cos^2A = sec^2 A

Important formulas:(1) Sin^2 A + cos^2 A = 1(2) cot A = cos A/sin A(3) 1/sin^2 A = cosec^2
