simplify-3(-2cos(x)+3cos^3(x))

simplify

- 3 (- 2 cos (x) + 3 cos^{3} (x))

6 cos (x) - 9 cos^{3} (x)

Solution steps

- 3 (- 2 cos (x) + 3 cos^{3} (x))

Expand

- 3 (- 2 cos (x) + 3 cos^{3} (x)) : 6 cos (x) - 9 cos^{3} (x)

= 6 cos (x) - 9 cos^{3} (x)

\frac{x + 5}{x ( x + 11 )}

(x^{2} + 3) (x^{2} - 3)

(tan^{4} (x) + tan^{3} (x) - tan (x) - 1) (cos^{2} (x))

(- 4 e^{- 4 x} + 3 x^{5})^{2}

(n + 1 - 2) (n + 1 + 2)
