- S1 E1 - A Preview of Calculus
March 4, 201033minCalculus is the mathematics of change, a field with many important applications in science, engineering, medicine, business, and other disciplines. Begin by surveying the goals of the series. Then get your feet wet by investigating the classic tangent line problem, which illustrates the concept of limits.Subscribe for $1.99/month for 2 month(s) and $7.99/month thereafter, or buy - S1 E2 - Review - Graphs, Models, and Functions
March 4, 201030minIn the first of two review episodes on precalculus, examine graphs of equations and properties such as symmetry and intercepts. Also explore the use of equations to model real life and begin your study of functions, which Professor Edwards calls the most important concept in mathematics.Subscribe for $1.99/month for 2 month(s) and $7.99/month thereafter, or buy - S1 E3 - Review - Functions and Trigonometry
March 4, 201030minContinue your review of precalculus by looking at different types of functions and how they can be identified by their distinctive shapes when graphed. Then review trigonometric functions, using both the right triangle definition as well as the unit circle definition, which measures angles in radians rather than degrees.Subscribe for $1.99/month for 2 month(s) and $7.99/month thereafter, or buy - S1 E4 - Finding Limits
March 4, 201031minJump into real calculus by going deeper into the concept of limits introduced in the first episode. Learn the informal, working definition of limits and how to determine a limit in three different ways: numerically, graphically, and analytically. Also discover how to recognize when a given function does not have a limit.Subscribe for $1.99/month for 2 month(s) and $7.99/month thereafter, or buy - S1 E5 - An Introduction to Continuity
March 4, 201031minBroadly speaking, a function is continuous if there is no interruption in the curve when its graph is drawn. Explore the three conditions that must be met for continuity, along with applications of associated ideas, such as the greatest integer function and the intermediate value theorem.Subscribe for $1.99/month for 2 month(s) and $7.99/month thereafter, or buy - S1 E6 - Infinite Limits and Limits at Infinity
March 4, 201031minInfinite limits describe the behavior of functions that increase or decrease without bound, in which the asymptote is the specific value that the function approaches without ever reaching it. Learn how to analyze these functions, and try some examples from relativity theory and biology.Subscribe for $1.99/month for 2 month(s) and $7.99/month thereafter, or buy - S1 E7 - The Derivative and the Tangent Line Problem
March 4, 201031minBuilding on what you've learned about limits and continuity, investigate derivatives, which are the foundation of differential calculus.

March 4, 201030minPractice several techniques that make finding derivatives relatively easy: the power rule, the constant multiple rule, sum and difference rules, plus a shortcut to use when sine and cosine functions are involved. Then see how derivatives are the key to determining the rate of change in problems involving objects in motion.Subscribe for $1.99/month for 2 month(s) and $7.99/month thereafter, or buy - S1 E9 - Product and Quotient Rules
March 4, 201031minLearn the formulas for finding derivatives of products and quotients of functions. Then use the quotient rule to derive formulas for the trigonometric functions not covered in the previous episode. Also investigate higher-order derivatives, differential equations, and horizontal tangents.Subscribe for $1.99/month for 2 month(s) and $7.99/month thereafter, or buy - S1 E10 - The Chain Rule
March 4, 201031minDiscover one of the most useful of the differentiation rules, the chain rule, which allows you to find the derivative of a composite of two functions. Explore different examples of this technique, including a problem from physics that involves the motion of a pendulum.Subscribe for $1.99/month for 2 month(s) and $7.99/month thereafter, or buy - S1 E11 - Implicit Differentiation and Related Rates
March 4, 201031minConquer the final strategy for finding derivatives: implicit differentiation, used when it's difficult to solve a function for y. Apply this rule to problems in related rates (for example, the rate at which a camera must move to track the space shuttle at a specified time after launch).Subscribe for $1.99/month for 2 month(s) and $7.99/month thereafter, or buy - S1 E12 - Extrema on an Interval
March 4, 201030minHaving covered the rules for finding derivatives, embark on the first of five episodes dealing with applications of these techniques. Derivatives can be used to find the absolute maximum and minimum values of functions, known as extrema, a vital tool for analyzing many real-life situations.Subscribe for $1.99/month for 2 month(s) and $7.99/month thereafter, or buy - S1 E13 - Increasing and Decreasing Functions
March 4, 201031minUse the first derivative to determine where graphs are increasing or decreasing. Next, investigate Rolle's theorem and the mean value theorem, one of whose consequences is that during a car trip, your actual speed must correspond to your average speed during at least one point of your journey.Subscribe for $1.99/month for 2 month(s) and $7.99/month thereafter, or buy - S1 E14 - Concavity and Points of Inflection
March 4, 201031minWhat does the second derivative reveal about a graph? It describes how the curve bends, whether it is concave upward or downward. Determine concavity much as you found the intervals where a graph was increasing or decreasing, except this time you'll use the second derivative.Subscribe for $1.99/month for 2 month(s) and $7.99/month thereafter, or buy - S1 E15 - Curve Sketching and Linear Approximations
March 4, 201032minBy using calculus, you can be certain that you have discovered all the properties of the graph of a function. After learning how this is done, focus on the tangent line to a graph, which is a convenient approximation for values of the function that lie close to the point of tangency.Subscribe for $1.99/month for 2 month(s) and $7.99/month thereafter, or buy - S1 E16 - Applications - Optimization Problems, Part 1
March 4, 201031minAttack real-life problems in optimization, which requires finding the relative extrema of different functions by differentiation.

March 4, 201031minUp until now, you've calculated a derivative based on a given function. Discover how to reverse the procedure and determine the function based on the derivative.
