3x3 Linear Systems of Equations
This lesson involves connecting graphical representations of systems of linear equations in three variables to the number of solutions of those systems.
Building Sequences and Series with a Spreadsheet
This lesson has students create sequences and series in a spreadsheet.
Cryptology and Matrices
This lesson involves using matrices to encode and decode a message.
From Rumor to Chaos
This lesson involves modeling the spread of a rumor and similar problems.
This lesson involves linear transformations from R2 to R2 represented by matrices. Note: R2 = R x R represents the set of all pairs of real numbers.
Parabolas and Matrices
This lesson involves using matrices to solve a system of three simultaneous linear equations.
Roots and Cobwebs
This lesson involves finding roots to equations using a method similar to those used by many calculators.
Sum of Infinite Geometric Series
This lesson involves clicking on a slider to see that the area of a square that has been systematically divided into an infinite number of pieces approaches 1.
