What is Calculus?

In a team of three:

What is calculus?

What is calculus used for?

What is Calculus?

We can start to figure that out by answering, “What do we do in calculus?”

1. Find tangent slopes

2. Find areas

Inherently connected

Tangents and Secants

What is a tangent?

A line that connects two points on a curve

A line that just barely touches a curve

An average rate of change

An instantaneous rate of change

Tangents and Secants

What is a tangent?

A line that connects two points on a curve

A line that just barely touches a curve

An average rate of change

Tangents and Secants

What is a secant?

A line that connects two points on a curve

A line that just barely touches a curve

An average rate of change

An instantaneous rate of change

Tangents and Secants

What is a secant?

A line that connects two points on a curve

A line that just barely touches a curve

An average rate of change

An instantaneous rate of change

Tangents and Secants

Tangent = instantaneous rate of change

Secant = average rate of change

Apply it!

If we tracked Jason Brown’s position as a function of time, we might see something like this:

Time (s)

Position (m)

Graph it!

What is Brown’s average velocity between 0 and 4s? 1 and 3s?
