prove (tan^2(θ))/(sec^2(θ))=sin(+cos(x))

prove

\frac{tan ^{2} ( θ )}{sec ^{2} ( θ )} = sin (+ cos (x))

False

Solution steps

\frac{tan ^{2} ( θ )}{sec ^{2} ( θ )} = sin (cos (x))

Show that the two sides are not equal

\Rightarrow False

4 cos^{2} (x) - 2 = 2 - 4 sin^{2} (x)

sin (3 x) = sin (x) (3 - 4 sin^{2} (x))

1 + sec (θ) tan (θ) sin (θ) = sec^{2} (θ)

2 - cos^{2} (θ) = 1 + sin^{2} (θ)

(tan (x)) (sin (x)) + cos (x) = sec (x)
