# Calculus Introduction

# Areas

We’ve been dealing with areas and volumes since geometry. Actually, we’ve been dealing with them since we figured out a square peg doesn’t fit in a round hole. Ever wonder how the math wizards figured out those volume equations? That’s right, they used calculus.

We’ll use calculus to find the area created by a graph. Later, we’ll add a third dimension to find the volume of shapes. Not just uniform shapes like cylinders, but wiggly vase-like shapes. Maybe we’ll throw in a T-Rex shaped volume, for a challenge. Who knew paleontologists use calculus, too?
