simplify e^{-t}u(t-1)

Solution

simplify

e^{- t} u (t - 1)

Solution

\frac{u ( t - 1 )}{e ^{t}}

Solution steps

e^{- t} u (t - 1)

Apply exponent rule:

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

= \frac{1}{e ^{t}} u (t - 1)

Multiply fractions:

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

= \frac{1 \cdot u ( t - 1 )}{e ^{t}}

Multiply:

1 \cdot u = u

= \frac{u ( t - 1 )}{e ^{t}}
