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

Solution

simplify

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

Solution

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

Solution steps

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

Apply exponent rule:

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

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

Multiply fractions:

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

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

Multiply:

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

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