simplify e^{-x}cos(y)

Solution

simplify

e^{- x} cos (y)

Solution

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

Solution steps

e^{- x} cos (y)

Apply exponent rule:

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

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

Multiply fractions:

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

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

Multiply:

1 \cdot cos (y) = cos (y)

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