Calculating the Determinant of a 2x2 Matrix
By Roy Peterson
In this learning activity you'll calculate the determinant of a 2x2 matrix.
In this animated object, learners use an algebraic formula to solve the following problem: An airplane travels a certain distance with the wind in the same amount of time that it takes to travel a shorter distance against the wind. Given a constant wind speed, what is the speed of the plane without a wind?
