TRIGONOMETRICAL RATIOS - POWER OF T-RATIOS

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).
