integral of 2/s

\int \frac{2}{s} d s

2 ln ∣ s ∣ + C

Solution steps

\int \frac{2}{s} d s

Take the constant out:

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

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

Use the common integral:

\int \frac{1}{s} d s = ln (∣ s ∣)

= 2 ln ∣ s ∣

Add a constant to the solution

= 2 ln ∣ s ∣ + C

x \to - 2 lim (\frac{x}{x - 2})

\int_{1}^{3} e^{x + 2} d x

\frac{\partial}{\partial t} (6 q (r, t)^{2} + 7 r^{3} - \frac{8}{t} - q (r, t) t)

n = 0 \sum \infty \frac{2}{n ^{2} + 6 n + 8}

(2 x - 5)^{2}
