Separable equations

Separable equations

Separable of variables is a method we use to find a general solution of a differential equation. The method involves separating all the y variables to the left hand side of the equation, and moving all the x variables to the right side. Afterwards, we integrate both sides of the equation and then isolate for y to find the general solution. If it is too hard to isolate for y, you can leave the answer as it is. We will also be looking at questions about particular solutions. These are solutions which involves finding the value of the constant, when given an initial value.

Notes:
A separable differential equation is in the following form:

f(y)dydx=g(x)f(y)\frac{dy}{dx}=g(x)

Where:
1. f(x)f(x) is a function in terms of yy.
2. g(x)g(x) is a function in terms of xx.

We want to convert the equation to the following form:
f(y)dy=g(x)dxf(y)dy=g(x)dx
so that we can integral both sides, and solve for yy.
