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

simplify

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

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

Solution steps

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

Apply exponent rule:

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

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

Multiply fractions:

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

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

Multiply the numbers:

1 \cdot 2 = 2

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

π (242) (402)

e^{- l n (- \frac{1}{2} - c)}

\frac{e ^{y - x}}{e ^{x - y}}

8 \cdot 1 0^{- 3} \cdot 9.81

e^{- 0.00053}
