expand a(-e^{-x}cos(x)-e^{-x}sin(x))

expand

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

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

Solution steps

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

Apply the distributive law:

a (b - c) = ab - a c

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

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

Apply minus-plus rules

+ (- a) = - a

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

\frac{\frac{d}{d x} ( x ^{3} ( x - 5 ) ^{2} )}{( x ^{2} + 4 ) ^{7}}

f, f = e^{2 x} δ (x - 1) + x^{3}

[2 a^{2} (a^{2} - b^{2})] m^{2}

\frac{3 s + 5}{s ( s ^{2} + s - 6 )}

(tan^{2} (14 x) - cot^{2} (14 x))^{2}
