Calculus

Integral Calc: Calculus Series (191 short videos) More than 100 videos on the harder math concepts because that’s what most people have the hardest time with, but our videos help anyone struggling with Pre-Algebra, Algebra, Geometry, Trigonometry, Calculus, and advanced math.

Definite Integrals and Riemann Sums - Full Video (33:57) How do definite and indefinite integrals differ? What do Riemann sums add up? And how far will “Cowpoke” chase his dream? This program tells all, beginning with a thorough examination of definite integrals and Riemann sums. Then, the pièce de résistance—the Fundamental Theorem of Calculus—is unveiled. A study of the area between two curves and the area between a curve and the x-axis rounds out the program.

Derivative Rules and Tangent Lines (23:29) What does an unemployed hardware salesman know about calculus? The answer to that and other questions can be found in this program, which features rugged tools for reducing the complexity of working with derivatives, including the Power Rule, e Rule, Natural Logarithm Rule, Product Rule, and Quotient Rule. Finding the equations of tangent lines and the Point-Slope Formula complete the program.

Functions and Limits (24:10) What is calculus, anyway, and how is it used? Answers to these and other questions can be found in section one of this program, along with a concise review of graphing and functions. Section two posits the intuitive definition of limits and follows up with numerous examples to demonstrate how to find a limit through substitution, factoring, and using conjugates.
