Unit 4.4: Introduction to Related Rates

Radians and the hypotenuse can be written as two related equations.

Hypotenuse Equation

H = 50 cos( θ )

Examples of Related Rates:

Finding the rate of surface area of a sphere when given radius and radius rate of change.

Finding the rate of change of 2 different objects when moving in different directions

What are Related Rates?

In AP Calculus AB, related rates are used to find how different quantities change with (most commonly) time.

These equations are usually connected to each other, and are used to find the rate of another equation.

Styled Derivative

dt = 0.01 θ/min
