Question

prove that tan²-sin²=tan²*1/cosec²​

Answer 1

Answer:

Given that :

= In RHS tan^2×1/cosec^2

= then, we know that according to trigonometric ratios 1/cosec^2 can be written as,

= 1/cosec^2= sin^2

= therefore, LHS= tan^2-sin^2

= we got answer as tan^2-sin^2

= so,LHS=RHS

Hope it helps u my friend

if it is not clear if u get any doubt ask me.....

thank you
