Definition: In calculus, differentiation is a process of finding the derivative of a function. This means that you are asked to find the rate at which one quantity changes with respect to another, and this change is measured in terms of how much of one variable you're changing while keeping the other constant. For example, if you have a function \( f(x) \), where \( x \) is the independent variable and \( y \) is the dependent variable, then differentiation is used when you are trying to
