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

expand

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

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

Solution steps

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

Apply the distributive law:

a (b + c) = ab + a c

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

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

Simplify

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

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

\frac{\frac{d ^{3}}{d x ^{3}} ( ( y ) 3 )}{( 3 x - 2 ) ^{5}}

3 x^{2} + 9 x^{2} + 9 x + 31

4 (x - 1) ln (x - 1)

\frac{I n x y}{I n z}

- 0.15 + \frac{h ( h - 0.15 ) + 0.0075}{h - 0.15}
