Solve the differential equation

Evaluate

$$f^{\prime }=a$$

Rewrite the expression

$$\frac{df}{da}=a$$

Transform the expression

$$df=ada$$

$$\text{Integrate the left-hand side of the equation with respect to }f\text{ and the right-hand side of the equation with respect to }a$$

$$\int 1df=\int ada$$

Evaluate

$$\int ada$$

$$\text{Use the property of integral }\int x^{n}dx=\frac{x^{n+1}}{n+1}$$

$$\frac{a^{1+1}}{1+1}$$

Add the numbers

$$\frac{a^2}{1+1}$$

Add the numbers

$$\frac{a^2}{2}$$

$$\text{Add the constant of integral }{C}_2$$

$$\frac{a^2}{2}+C_2,C_2\in \mathbb{R}$$
