A differential equation is a mathematical equation for an unknown function of one or several variables that relates the values of the function itself and its derivatives of various orders. An ordinary differential equation (ODE) is a differential equation containing one or more derivatives of a function and their rates of change with respect to the function itself; it can be used to model a wide variety of phenomena. Differential equations can be used to describe many phenomena in physics, including sound, heat, electrostatics, electrodynamics, fluid dynamics, elasticity, quantum mechanics, and general relativity.

Yeah. Okay. If I ask you what's the derivative of X. Y. You would say X. This is with respect to X. X times the derivative of Y plus Y times the derivative of X. Which is what we have here. So this site turns into X. Y. Prime and this side turns into the square root of X. Okay, so now what I'm gonna do is if I have the derivative here now I'm going to integrate. Okay, so want to integrate. So the integral of the derivative is the stuff. And this gives you X to the three halves over three halves plus C, divide everything by X. And you get Y equals two thirds next to the one half plus C over X. And that is the solution to this differential equation.
