Khan Academy: Intro to Complex Analysis: Basic Complex Analysis

Statistics come front and center in this unit all about analyzing discrete data. Real-world situations yield data sets that the class then uses to tease out connections and conclusions. Beginning with the basic histogram and...

This video gives an excellent overview of the different representations of a complex number. First, Sal reviews a pictorial representation of a complex number as an Argand diagram, then shows how to find the modulus and the argument of a...

What makes data big? The 38th installment in the series Crash Course Statistics provides a definition of big data and its origins. It shows various methods and resources on how to collect big data and how companies use big data for a...

An instructional video describing complex conjugates. Complex conjugates are defined and then used to simplify a problem in which a complex number is divided by another complex number. [8:03]

In this video lesson students learn to use exponential form to find complex roots.

A video showing the step-by-step solution to a difficult determinant problem from the IIT-JEE. This is problem 53 from Paper 1 of the 2010 exam. A 3 X 3 matrix is given in terms of z and omega, where omega is defined as a complex number...

Video works through six problems from the California Standards Test. Three problems involve simplifying rational expressions, one of which uses exponent rules. Two problems involve graphing complex numbers or reading them from graphs....

Sal introduces the basic idea of combinations.

Learn about arcsine, arccosine, and arctangent, and how they can be used to solve for a missing angle in right triangles.

Sal explains what it means for a polynomial to be a factor of another polynomial, and what it means for a polynomial to be divisible by another polynomial. [5:25]
