expand (3sin(x)-3)(2cos(x)+1)

expand

(3 sin (x) - 3) (2 cos (x) + 1)

3 sin (x) + 3 sin (2 x) - 6 cos (x) - 3

Solution steps

(3 sin (x) - 3) (2 cos (x) + 1)

Apply FOIL method

(3 sin (x) - 3) (2 cos (x) + 1) : 3 sin (x) + 3 sin (2 x) - 6 cos (x) - 3

= 3 sin (x) + 3 sin (2 x) - 6 cos (x) - 3

\frac{s + 2}{( s + 3 ) ( s - 1 )}

\frac{s ^{2}}{( s ^{2} + 4 ) ( s ^{2} - s + w ^{2} )}

(- \frac{1}{3} x + 1)^{3}

\frac{\partial}{\partial x} ((z) (3 x + 5 x y - 2 y^{2}))

\frac{x + 3}{( x - 5 ) ( x - 3 )}
