simplify e^{-2t}*cos(4t)

Solution

simplify

e^{- 2 t} \cdot cos (4 t)

Solution

\frac{cos ( 4 t )}{e ^{2 t}}

Solution steps

e^{- 2 t} cos (4 t)

Apply exponent rule:

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

= \frac{1}{e ^{2 t}} cos (4 t)

Multiply fractions:

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

= \frac{1 \cdot cos ( 4 t )}{e ^{2 t}}

Multiply:

1 \cdot cos (4 t) = cos (4 t)

= \frac{cos ( 4 t )}{e ^{2 t}}
