Integral of 7/x dx

You have entered [src]

$$\int\limits_{0}^{1} \frac{7}{x}\, dx$$

Integral(7/x, (x, 0, 1))

Detail solution

The integral of a constant times a function is the constant times the integral of the function:

$\int \frac{7}{x}\, dx = 7 \int \frac{1}{x}\, dx$
1. The integral of $\frac{1}{x}$ is $\log{\left(x \right)}$ .
So, the result is: $7 \log{\left(x \right)}$
Add the constant of integration:

$7 \log{\left(x \right)}+ \mathrm{constant}$

The answer is:

$7 \log{\left(x \right)}+ \mathrm{constant}$
