sec^6tetha-tan^6tetha=1+3tan^2tetha+3tan^4tetha
sec^6tetha=1+3tan^2tetha+3tan^4tetha+tan^6tetha...
PROOF:-
sec6 θ = (sec2 θ)3 = (1 + tan2 θ)3
= (1)3 + (tan2 θ)3 + 3 × 1 × tan2 θ (1 + tan2 θ)
= 1 + tan6 θ + 3 tan2 θ sec2 θ
sec^6tetha-tan^6tetha=1+3tan^2tetha+3tan^4tetha
sec^6tetha=1+3tan^2tetha+3tan^4tetha+tan^6tetha...
PROOF:-
sec6 θ = (sec2 θ)3 = (1 + tan2 θ)3
= (1)3 + (tan2 θ)3 + 3 × 1 × tan2 θ (1 + tan2 θ)
= 1 + tan6 θ + 3 tan2 θ sec2 θ
Triyan:
the identity i used is 1+tan2tetha=sec2tetha
