Use the substitution to solve the initial value problem {eq}yy' + x = \sqrt {x^2 + y^2} {/eq} with {eq}y(4) = \sqrt 20 {/eq}. Explain each steps.

Initial value Problem

An ordinary differential equation is the relation between a function of a single variable, and its derivatives. The function which satisfies the equation is a general solution which contains the arbitrary constants. When there is initial condition, then it is known as initial value problem. Applying initial condition, a particular solution can be established.
