$\frac{dy}{dx}\frac{\cos\left(x\right)}{\cos\left(x\right)}+\frac{y\sin\left(x\right)}{\cos\left(x\right)}=\frac{1}{\cos\left(x\right)}$
Learn how to solve problems step by step online. dy/dxcos(x)+ysin(x)=1. Divide all the terms of the differential equation by \cos\left(x\right). 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{\sin\left(x\right)}{\cos\left(x\right)} and Q(x)=\frac{1}{\cos\left(x\right)}. 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.
