Popular Calculus >

integral of-3/(e^t)

Solution

\int - \frac{3}{e ^{t}} d t

Solution

\frac{3}{e ^{t}} + C

Solution steps

\int - \frac{3}{e ^{t}} d t

Take the constant out:

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

= - 3 \cdot \int \frac{1}{e ^{t}} d t

Apply u-substitution

= - 3 \cdot \int \frac{1}{u ^{2}} d u

Apply the Power Rule

= - 3 (- \frac{1}{u})

Substitute back

u = e^{t}

= - 3 (- \frac{1}{e ^{t}})

Simplify

- 3 (- \frac{1}{e ^{t}}) : \frac{3}{e ^{t}}

= \frac{3}{e ^{t}}

Add a constant to the solution

= \frac{3}{e ^{t}} + C
