prove sec^2(x)=sin^2(x)+cos^2(x)

prove

sec^{2} (x) = sin^{2} (x) + cos^{2} (x)

False

Solution steps

sec^{2} (x) = sin^{2} (x) + cos^{2} (x)

Show that the two sides are not equal

\Rightarrow False

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

tan^{2} (a) = (tan (a))^{2}

(1 - cos (θ^{2})) (1 + cot (θ^{2})) = 1

cos (2 x) = \frac{2 - sec ^{2} ( x )}{sec ^{2} ( x )}

cot (y) = \frac{sin ( 2 y )}{1 - cos ( 2 y )}
