An Introduction to Calculus
Calculus Study of how things change Allows us to model real-life situations very accurately
Topics (not in order) Limits Slope of a curve Tangent Lines Extreme values of a curve Area under a curve/volume of a region Lengths Riemann Sums (Finite & Infinite) Rates of Change
Before Calculus After Calculus Find slope of a line Calculate average speed of a car Calculate area/volume of rigid geometric figures Find slope of a curve at a point Determine exact speed of a car at a particular time Determine area/volume of any figure under any curve/region
Two Main Problems to Solve: I. Tangent Line Problem: How do you find the equation of the tangent line to the graph of a curve at a particular point? II. Area Under Curve Problem: How can you find the area underneath a curve and above the x-axis?
f(c) f(c+ x c c+ x Secant line Tangent line Secant line c+ x f(c+ x
As x decreases ( x0), secant line approaches the tangent line.

As the number of rectangles increases, the sum of their areas approaches the exact area of the curve.
