expand sin(x)(4cos^2(x)+2cos(x)-1)

expand

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

4 cos^{2} (x) sin (x) + sin (2 x) - sin (x)

Solution steps

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

Apply the distributive law:

m (a + b + c) = ma + mb + m c

sin (x) (4 cos^{2} (x) + 2 cos (x) - 1) = sin (x) \cdot 4 cos^{2} (x) + sin (x) \cdot 2 cos (x) + sin (x) (- 1)

= sin (x) \cdot 4 cos^{2} (x) + sin (x) \cdot 2 cos (x) + sin (x) (- 1)

Simplify

sin (x) \cdot 4 cos^{2} (x) + sin (x) \cdot 2 cos (x) + sin (x) (- 1) : 4 cos^{2} (x) sin (x) + sin (2 x) - sin (x)

= 4 cos^{2} (x) sin (x) + sin (2 x) - sin (x)

\frac{d}{d y} ((x) ((1 + 6 x)^{4}))

x^{2} (- a sin (x) + b cos (x))

(x - 8) \cdot (x + 64)

\frac{1}{1 - x} - \frac{1}{x}

\frac{1}{3} (cosh (9 e ni) - cosh (6 e ni))
