expand sin(x)(2*cos(x)-1)

expand

sin (x) (2 \cdot cos (x) - 1)

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

Solution steps

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

Apply the distributive law:

a (b - c) = ab - a c

sin (x) (2 cos (x) - 1) = sin (x) \cdot 2 cos (x) - sin (x) \cdot 1

= sin (x) \cdot 2 cos (x) - sin (x) \cdot 1

Simplify

sin (x) \cdot 2 cos (x) - sin (x) \cdot 1 : 2 cos (x) sin (x) - sin (x)

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

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

(x - 3) e^{x}

\frac{( 8 + 3 x ) ^{2}}{16}

(x^{2} - y^{2}) d x

2 cos (t) (4 sin (t) - 3 tan (t))
