Calculus AB

Calculus AB covers the fundamental concepts of differential and integral calculus, preparing students for advanced mathematical applications.

Basic Concepts

Derivatives and Differentiation

Measuring Change

Derivatives measure how a function changes—like the speed of a car at a specific instant. Differentiation is the process of finding that rate.

What is a Derivative?

The derivative of \( f(x) \) at a point tells us the function’s instantaneous rate of change there. It’s like asking, "How fast am I going right now?"

The Power Rule

For \( f(x) = x^n \), the derivative is \( f'(x) = n x^{n-1} \).

Why This Is Cool

Derivatives help us:

  • Find slopes of curves
  • Understand how things grow or shrink instantly
  • Maximize and minimize quantities (like profits!)

How to Differentiate

  • Apply rules: like the power, product, and quotient rules.
  • Plug in the value if you need the derivative at a specific point.

Everyday Derivatives

From tracking speed on your fitness app to figuring out how fast a cup of coffee cools, derivatives are everywhere!

Examples

  • The derivative of \( f(x) = x^2 \) is \( 2x \), so at \( x = 3 \), the slope is 6.

  • The slope of the tangent line to \( y = \sin(x) \) at \( x = 0 \) is 1.

In a Nutshell

Derivatives tell us how fast things change at any moment.
