This chapter presents the general solutions of differential equations and boundary problems. Determining a general solution is, as regards calculation, simpler than determining a particular solution with given initial conditions; because it is unnecessary to find all the coefficients of decomposition into ...

Example 1 - Finding General Solutions to Differential Equations Using Antidifferentiation Use antidifferentiation to determine the general solution to the differential equation dydx=6xy+2. Step 1: Rewrite the given differential equation in the form f(y)dy=g(x)dx. We can write the ...
The solution of the differential equation will always be an explicit function. But when we are writing the differential equation, then it can be an implicit function. To separate the terms and integrate is the only challenge to solve the differential equations....
