Will the ap calculus ab exam have law of cooling?

The AP Calculus AB exam does not specifically test the Law of Cooling as a named concept. However, the differential equation that represents the Law of Cooling (a separable differential equation) could appear as a problem. You'll need to be able to solve separable differential equations and apply initial conditions. So while you won't be asked to *name* the Law of Cooling, you might be asked to solve a problem that uses its underlying mathematical model.
