simplify e^{-2x}cos(4x)

Solution

simplify

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

Solution

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

Solution steps

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

Apply exponent rule:

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

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

Multiply fractions:

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

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

Multiply:

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

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