expand-2(e^xcos(x)-e^xsin(x))

expand

- 2 (e^{x} cos (x) - e^{x} sin (x))

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

Solution steps

- 2 (e^{x} cos (x) - e^{x} sin (x))

Apply the distributive law:

a (b - c) = ab - a c

a = - 2, b = e^{x} cos (x), c = e^{x} sin (x)

= - 2 e^{x} cos (x) - (- 2) e^{x} sin (x)

Apply minus-plus rules

- (- a) = a

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

(- 2 - 4 i)^{8}

\frac{2 ( 12 + 2 x )}{3 ( 4 + x )}

20 + 8

(sin (t) - 1) (cos (t))

(x - 1) (1 + x)
