A mathematical function or expression that is being integrated in calculus.

Conversation

I was studying calculus and got confused about the integrand in my notes.

Oh, I remember that! The integrand is just the function you need to integrate.

Right, but how do I know which function to choose?

Just look for the expression that represents the area under the curve.

Root Explanation

Integrand → It is formed from "integer" (from Latin *integer*, meaning whole or untouched) and "-and" (a suffix used to indicate a function or process). The word "integrand" refers to a function that is to be integrated, thus representing a whole or complete function in the context of calculus.

Memory Tip

Think of a function that is 'whole' ('integer') and is being processed for integration ('-and'). This helps you remember that an integrand is a function that you integrate.
