simplify e^{-0.4t}cos(at)

Solution

simplify

e^{- 0.4 t} cos (a t)

Solution

\frac{cos ( t a )}{e ^{0.4 t}}

Solution steps

e^{- 0.4 t} cos (a t)

Apply exponent rule:

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

= \frac{1}{e ^{0.4 t}} cos (t a)

Multiply fractions:

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

= \frac{1 \cdot cos ( a t )}{e ^{0.4 t}}

Multiply:

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

= \frac{cos ( t a )}{e ^{0.4 t}}
