integral of 1/(100+2t)

\int \frac{1}{100 + 2 t} d t

\frac{1}{2} ln ∣ 100 + 2 t ∣ + C

Solution steps

\int \frac{1}{100 + 2 t} d t

Apply u-substitution

: \int \frac{1}{2 u} d u

= \int \frac{1}{2 u} d u

Take the constant out:

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

= \frac{1}{2} \cdot \int \frac{1}{u} d u

Use the common integral:

\int \frac{1}{u} d u = ln (∣ u ∣)

= \frac{1}{2} ln ∣ u ∣

Substitute back

u = 100 + 2 t

= \frac{1}{2} ln ∣ 100 + 2 t ∣

Add a constant to the solution

= \frac{1}{2} ln ∣ 100 + 2 t ∣ + C

x \to + 0 lim (3 x)

\frac{\partial}{\partial y} (1 + y e^{x y})

\int_{1}^{4} (x ln (x)) d x

\frac{d}{d x} (y e^{- x})

\frac{d P}{d t} = a P - b P^{2}
