MATHEMATICS S6 UNIT 4: INTEGRATION.
About Course
In calculus, the term “primitive” is an older, but still perfectly valid, synonym for antiderivative or indefinite integral.
So, when someone talks about finding the “primitive” of a function, they are asking you to perform the operation of integration to find a function whose derivative is the given function.
Let’s break down the concept using the more common modern terminology:
What is a Primitive (Antiderivative / Indefinite Integral)?
Given a function , a function is called a primitive (or antiderivative) of if the derivative of is .
In mathematical notation: If , then is a primitive of

The Constant of Integration ()
Here’s a crucial point: if is a primitive of , then is also a primitive of , where is any arbitrary real number constant. This is because the derivative of any constant is zero.
