- the derivative is the ratio of how one quantity changes with respect to another
- the integral is the area under the curve

So what's a differential equation? According to here "A differential equation is any equation which contains derivatives, either ordinary derivatives or partial derivatives. "

This doesn't make any sense because how is a differential equation different than a derivative? If you are abstractly given a function \(\displaystyle f(x)=x^2\) then you can't say it's a dirivative or antidirvate of anything.
