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

Solution

simplify

cos (x) e^{- 2 x}

Solution

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

Solution steps

cos (x) e^{- 2 x}

Apply exponent rule:

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

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

Multiply fractions:

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

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

Multiply:

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

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