expand cos(x)(cos(2x)-sin(x))

expand

cos (x) (cos (2 x) - sin (x))

cos (x) cos (2 x) - cos (x) sin (x)

Solution steps

cos (x) (cos (2 x) - sin (x))

Apply the distributive law:

a (b - c) = ab - a c

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

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

(v^{2} + u^{2}) v^{2} + u^{2}

2646 (s + s^{'})^{2}

4 x^{3 (6 x^{5} - 2 x + 3)}

\frac{1}{5} (\frac{2178}{ln ( 3 )} + 25)

\frac{d ^{2}}{d x ^{2}} ((sin (x))^{2}) - 2 (1 - cos (x))
