Khan Academy: Green's Theorem: Green's Theorem Proof (Part 2)

Can they put it all together? Ninth graders apply what they know about proofs and triangle congruence to complete these proofs. These proofs go beyond the basic triangle congruence proofs and use various properties, theorems, and...

Sal shows two ways to calculate the coefficients of a binomial expansion quickly. The first method shows the relationship between PascalÕs triangle and the coefficients, and the second method shows an even faster way to write the...

Part 1 of the proof of Green's Theorem

Explains how to find the area of a Koch snowflake which is represented by an infinite geometric series. Continuation of previous video "Area of Koch Snowflake (part 1) - Advanced" [6:32]

Video lesson continuing the problem from the previous video on finding the surface area along a closed curve using line integrals. Two line integrals are set up and solved and added to the area found previously. [9:58]

This video tutorial lesson [9:52] provides a proof for the Pythagorean Theorem by breaking a right triangle into two similar triangles and setting up ratios of corresponding sides.

The video tutorial lesson [9:36] explains how to use the Pythagorean theorem to find the length of the hypotenuse or the length of one of the legs. Introduces the relationship between the length of the legs and the length of the...

Video shows how to divide complex numbers by using complex conjugates in general terms and then with a specific example. [8:58]
