- 1Variable Separable Method1. Separate the variables (get all the x and all the y on separate sides)
2. Integrate, then rearrange to obtain the general solution 'y = ...'
3. Use the given condition to find the particular solution - 2Integration factorα(x) = exp Z
p(x)dx - 3Integration factor method1. Find the integration factor
Multiply both sides of the differential equation by the integration factor
2. Use the product rule to re-write the left hand side
3. Integrate both sides with respect to x, then rearrange to obtain the general solution
