simplify-cos(30+x)

simplify

- cos (3 0^{\circ} + x)

- \frac{3}{2} cos (x) + \frac{1}{2} sin (x)

Solution steps

- cos (3 0^{\circ} + x)

Rewrite using trig identities

= - (\frac{3}{2} cos (x) - \frac{1}{2} sin (x))

Simplify

- (\frac{3}{2} cos (x) - \frac{1}{2} sin (x)) : - \frac{3}{2} cos (x) + \frac{1}{2} sin (x)

= - \frac{3}{2} cos (x) + \frac{1}{2} sin (x)

cot (- 1 (tan (\frac{5 n}{3})))

cot (arccos (\frac{x}{17}))

cos (n π^{1})

\frac{tan ( - x )}{tan ( x )}

sin (θ) + sin (θ + 2 π) + sin (θ + 4 π)
