When a derivative is expressed with both variables, it is very likely to have been differentiated using implicit differentiation. It becomes important to separate the variables and differentiate each side separately. Then, you may, or may not be able to write the resulting equation using function notation, depending on the equation itself.

Things you should be able to do after today:

- integrate derivatives that are expressed in terms of both x and y
- use separable differentiable equations to integrate derivatives in terms of both x and y where substitution may be needed
