prove sin(x)=tan^2(x)cos^2(x)

prove

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

False

Solution steps

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

Show that the two sides are not equal

For

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

plug in

x = 1

sin (1) = 0.84147 \dots

sin (1)

Refine to a decimal form

= 0.84147 \dots

tan^{2} (1) cos^{2} (1) = 0.70807 \dots

tan^{2} (1) cos^{2} (1)

Refine to a decimal form

= 0.70807 \dots

The two sides are not equal

\Rightarrow False

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

sin (3 x) = 2 \cdot sin (\frac{3 x}{2}) \cdot cos (\frac{3 x}{2})

\frac{sin ( 9 x ) - sin ( 3 x )}{cos ( 9 x ) - cos ( 3 x )} = - \frac{cos ( 6 x )}{sin ( 6 x )}

(sec (a) - tan (a)) (csc (a) + 1) = cot (a)

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