simplify-sin(arccos(x))

simplify

- sin (arccos (x))

- 1 - x^{2}

Solution steps

- sin (arccos (x))

Use the following identity:

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

= - 1 - x^{2}

sin (arctan (2 a))

\frac{1}{tan ( \frac{7 π}{2} - x )}

\frac{1}{sec ^{2} ( x ) - 1}

- 3 sin (4 x + \frac{π}{2})

tan (arctan (\frac{1}{x}))
