simplify e^{-2t}(cos(2t)-1)

simplify

e^{- 2 t} (cos (2 t) - 1)

\frac{cos ( 2 t ) - 1}{e ^{2 t}}

Solution steps

e^{- 2 t} (cos (2 t) - 1)

Apply exponent rule:

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

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

Multiply fractions:

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

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

1 \cdot (cos (2 t) - 1) = cos (2 t) - 1

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

(2 + x)^{- 3}

(\frac{4}{3})^{6}
