Khan Academy: 2 D Divergence Theorem: 2 D Divergence Theorem

Isn't paper pushing supposed to be boring? Learners attempt a paper-pushing puzzle to develop ideas about angles inscribed on a diameter of a circle. Learners then formalize Thales' theorem and use geometric properties to develop a proof...

Price increases in real life aren't enjoyable, but Sal's enthusiasm and easygoing explanation makes the question on increasing prices on the practice SAT fun! Showing students how to easily work through problems involving the Pythagorean...

The last video in a three-part series on the Binomial Theorem from the Khan Academy. This segment illustrates how the Binomial Theorem is directly related to combinatorics using (a + b)^3 as an example. Students can clearly see how a...

Video lesson introducing the mean value theorem by providing the theorem and explaining it visually with an arbitrary graph and an example about driving. Includes an example of using the mean value theorem with a specific function. [16:48]

This video tutorial is n introduction to the Pythagorean theorem. The instructor explains how to use the Pythagorean theorem to find the length of the hypotenuse or the length of one of the legs. At the end of the video, practice...

Explanation and proof of angle bisector theorem. [8:35]

The polynomial remainder theorem says that for a polynomial p(x) and a number a, the remainder on division by (x-a) is p(a). This might not be very clear right now, but you will understand this much better after watching these examples....

Use the PRT (Polynomial Remainder Theorem) to determine the factors of polynomials and their remainders when divided by linear expressions. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a...

Sal finds the remainder of (-3x^3-4x^2+10x-7) divided by (x-2) using the PRT (Polynomial Remainder Theorem). [3:31]
