simplify te^{-t}cos(3t)

Solution

simplify

t e^{- t} cos (3 t)

Solution

\frac{t cos ( 3 t )}{e ^{t}}

Solution steps

t e^{- t} cos (3 t)

Apply exponent rule:

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

= \frac{1}{e ^{t}} t cos (3 t)

Multiply fractions:

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

= \frac{1 \cdot t cos ( 3 t )}{e ^{t}}

Multiply:

1 \cdot t = t

= \frac{t cos ( 3 t )}{e ^{t}}
