Integral of 2x/y dx

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

   $$\int \frac{2 x}{y}\, dx = \frac{\int 2 x\, dx}{y}$$

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

      $$\int 2 x\, dx = 2 \int x\, dx$$

      1. The integral of $x^{n}$ is $\frac{x^{n + 1}}{n + 1}$ when $n \neq -1$:

         $$\int x\, dx = \frac{x^{2}}{2}$$

      So, the result is: $x^{2}$

   So, the result is: $\frac{x^{2}}{y}$

2. Add the constant of integration:

   $$\frac{x^{2}}{y}+ \mathrm{constant}$$

The answer is:

$$\frac{x^{2}}{y}+ \mathrm{constant}$$
