Differential Equations

Rates of Change

Formulating Differential Equations
You can use differential equations to model the rate of change of a
variable
If a is proportional to b then a = kb , and we can find k (the constant of
proportionality) by plugging in known values of
a and b
We can use this idea to formulate a differential equation:

Solving Differential Equations

If not enough information to find c then the equation you have is the
general solution
If you can sub in values to find c then the new equation (after
subbing to find
c ) is a particular solution
Can solve through separating variables:
