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

prove

- sin^{2} (x) - cos^{2} (x) = - 1

True

Solution steps

- sin^{2} (x) - cos^{2} (x) = - 1

Use the Pythagorean identity:

cos^{2} (x) + sin^{2} (x) = 1

- cos^{2} (x) - sin^{2} (x) = - 1

\Rightarrow True

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

\frac{tan ( θ ) cos ( θ )}{sin ( θ )} = 1

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

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

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