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

simplify

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

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

Solution steps

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

Apply exponent rule:

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

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

Multiply fractions:

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

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

Multiply the numbers:

1 \cdot 4 = 4

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

1.5 \times 1 0^{- 2}

1.5 \times 1 0^{- 4}

1.5 \times 1 0^{- 3}

(x^{2} - 13) e^{- x}

\frac{e ^{- n^{2} - 2 n - 1}}{e ^{- n^{2}}}
