integral of-0.056e^{-0.025x}

\int - 0.056 e^{- 0.025 x} d x

2.24 e^{- 0.025 x} + C

Solution steps

\int - 0.056 e^{- 0.025 x} d x

Take the constant out:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= - 0.056 \cdot \int e^{- 0.025 x} d x

Apply u-substitution

: \int - \frac{1}{0.025} e^{u} d u

= - 0.056 \cdot \int - \frac{1}{0.025} e^{u} d u

Take the constant out:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= - 0.056 (- \frac{1}{0.025} \cdot \int e^{u} d u)

Simplify

= - 0.056 (- 40 \cdot \int e^{u} d u)

Use the common integral:

\int e^{u} d u = e^{u}

= - 0.056 (- 40 e^{u})

Substitute back

u = - 0.025 x

= - 0.056 (- 40 e^{- 0.025 x})

Simplify

= 2.24 e^{- 0.025 x}

Add a constant to the solution

= 2.24 e^{- 0.025 x} + C

\int \frac{5}{4 x ^{2} + 9} d x

\int \frac{3 e ^{x}}{2 - e ^{x}} d x

\int 3 e^{- t} sin (t) d t

\int x^{2} \cdot ln (x^{3}) d x

\int (7 x + e^{2 x}) d x
