Question

tan square A by 1+tan square a +cot square a by 1+cot square a is equal to 1

Answer 1

Answer:

Step-by-step explanation:

Tan^2 A/1+Tan^2 A/1+Cot^2 A = 1

Tan^2 A/Sec^2 A/Cosec^2 A = 1 (1+Tan^2 A=Sec^2 and 1+Cot^2 A= Cosec^2A)

Tan^2 A/1/Cos^2 A/1/Sin^2 A = 1

Tan^2 A / Tan^2 A= 1

1 = 1

Thus LHS = RHS
