expand (cos^4(t)-2/3 cos^6(t))cos(2t)

expand

(cos^{4} (t) - \frac{2}{3} cos^{6} (t)) cos (2 t)

cos (2 t) cos^{4} (t) - cos (2 t) \frac{2}{3} cos^{6} (t)

Solution steps

(cos^{4} (t) - \frac{2}{3} cos^{6} (t)) cos (2 t)

= cos (2 t) (cos^{4} (t) - \frac{2}{3} cos^{6} (t))

Apply the distributive law:

a (b - c) = ab - a c

cos (2 t) (cos^{4} (t) - \frac{2}{3} cos^{6} (t)) = cos (2 t) cos^{4} (t) - cos (2 t) \frac{2}{3} cos^{6} (t)

= cos (2 t) cos^{4} (t) - cos (2 t) \frac{2}{3} cos^{6} (t)

d x (x - 3) (y - 4)

i (x + y i)^{2}

lo g_{4} (10 x)
