prove cosh^{(2)}(x)-sinh^{(2)}(x)=1

prove

cosh^{(2)} (x) - sinh^{(2)} (x) = 1

True

Solution steps

cosh^{2} (x) - sinh^{2} (x) = 1

Use the Hyperbolic identity:

cosh^{2} (x) - sinh^{2} (x) = 1

\Rightarrow True

sin (2 x) - cos (2 x) = 1 - 2 cos (2 x)

cot^{2} (x) tan (x) sin (x) = cos (x)

tan (x) (csc^{(2)} (x) - 1) = cot (x)

sin^{4} (θ) - cos^{4} (θ) = 2 sin (θ) - 1

tan (x) - 3 = 0
