expand-4sin(2)(x+pi/2)

expand

- 4 sin (2) (x + \frac{π}{2})

- 4 sin (2) x - 2 π sin (2)

Solution steps

- 4 sin (2) (x + \frac{π}{2})

Apply the distributive law:

a (b + c) = ab + a c

a = - 4 sin (2), b = x, c = \frac{π}{2}

= - 4 sin (2) x + (- 4 sin (2)) \frac{π}{2}

Apply minus-plus rules

+ (- a) = - a

= - 4 sin (2) x - 4 \cdot \frac{π}{2} sin (2)

4 \cdot \frac{π}{2} sin (2) = 2 π sin (2)

= - 4 sin (2) x - 2 π sin (2)

(l^{2} - 1 + e)^{2}

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

\frac{2 x ^{3}}{( 4 x ^{3} - 7 ) ^{3}}

(x + h)^{2} + 3

(3 x^{2} + 1) e^{x}
