simplify e^{-at}cos(w)tu(t)

Solution

simplify

e^{- a t} cos (w) t u (t)

Solution

e^{- a t} t^{2} u cos (w)

Solution steps

e^{- a t} cos (w) t u (t)

Apply exponent rule:

a^{b} \cdot a^{c} = a^{b + c}

tt = t^{1 + 1}

= e^{- a t} cos (w) u t^{1 + 1}

Add the numbers:

1 + 1 = 2

= e^{- a t} cos (w) u t^{2}
