prove sin(0)=(0)^3

Solution

prove

sin (0) = (0)^{3}

True

Solution steps

sin (0) = 0^{3}

Manipulating left side

sin (0)

Simplify

= 0

Manipulating right side

0^{3}

Simplify

= 0

We showed that the two sides could take the same form

\Rightarrow True

tan (2 x) = - \frac{arctan ( - \frac{4}{3} )}{2}

cos (0 + \frac{π}{2}) = - sin (0)

sin^{(2)} (\frac{a}{2}) = \frac{1 - cos ( a )}{2}

\frac{1 + sec ( x )}{tan ( x )} = cot (x) + csc (x)

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