prove sin^2(200)=sin(200)sin(200)

prove

sin^{2} (20 0^{\circ}) = sin (20 0^{\circ}) sin (20 0^{\circ})

True

Solution steps

sin^{2} (20 0^{\circ}) = sin (20 0^{\circ}) sin (20 0^{\circ})

Manipulating right side

sin (20 0^{\circ}) sin (20 0^{\circ})

Simplify

sin (20 0^{\circ}) sin (20 0^{\circ}) : sin^{2} (20 0^{\circ})

= sin^{2} (20 0^{\circ})

We showed that the two sides could take the same form

\Rightarrow True

\frac{( 1 + tan ^{2} ( x ) )}{tan ^{2} ( x )} = csc^{2} (x)

sin (5 x) - sin (x) = 2 cos (3 x) sin (2 x)

tan (\frac{π}{3}) sin (\frac{2}{3} π) = 1 + sin (\frac{π}{6})

csc (2 x) = \frac{2 3}{3}

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