prove tan^4(x)=sec^4(x)-sec^2(x)

prove

tan^{4} (x) = sec^{4} (x) - sec^{2} (x)

False

Solution steps

tan^{4} (x) = sec^{4} (x) - sec^{2} (x)

Show that the two sides are not equal

\Rightarrow False

sin^{2} (x) cos (x) - cos (x) = - cos^{3} (x)

cot (x) = \frac{- cos ^{2} ( x )}{( sin ( x ) + 1 ) ^{2}}

(1 - tan^{2} (θ)) = sec^{2} (θ) - 4 tan^{2} (θ)

sin (x) (sin (2 x)) = sin (3 x)

(cos (θ))^{2} (sec (θ))^{2} = 1
