$\frac{x^2}{x^2}\frac{dy}{dx}+\frac{xy}{x^2}=\frac{\sin\left(x\right)}{x^2}$
Learn how to solve integrals of polynomial functions problems step by step online. Solve the differential equation x^2dy/dx+xy=sin(x). Divide all the terms of the differential equation by x^2. Simplifying. We can identify that the differential equation has the form: \frac{dy}{dx} + P(x)\cdot y(x) = Q(x), so we can classify it as a linear first order differential equation, where P(x)=\frac{1}{x} and Q(x)=\frac{\sin\left(x\right)}{x^2}. In order to solve the differential equation, the first step is to find the integrating factor \mu(x). To find \mu(x), we first need to calculate \int P(x)dx.
