simplify e^{-at}sin(wt)u(t)

simplify

e^{- a t} sin (wt) u (t)

\frac{t u sin ( tw )}{e ^{a t}}

Solution steps

e^{- a t} sin (wt) u (t)

Apply exponent rule:

a^{- b} = \frac{1}{a ^{b}}

= \frac{1}{e ^{a t}} t u sin (tw)

Multiply fractions:

a \cdot \frac{b}{c} = \frac{a \cdot b}{c}

= \frac{1 \cdot sin ( wt ) u t}{e ^{a t}}

Multiply:

1 \cdot sin (wt) = sin (wt)

= \frac{t u sin ( tw )}{e ^{a t}}
