Power of T-Ratios –
We denote :-
(i) (sin θ)² by sin² θ
(ii) (cos θ)² by cos² θ
(iii) (tan θ)² by tan² θ
(iv) (sin θ)³ by sin³ θ
(v) (cos θ)³ by cos³ θ
(vi) (tan θ)³ by tan³ θ
For other cases such as where power is given 4, 5, 6, 7, ………………..etc. result must be as per power given (power will be different as given or suggested).
