Simply shows multiplication of a vector by a scalar. Adjust he slider to adjust the multiple. Drag the point at the end of vector v to change the original vector.
This is a solver for problems involving the time value of money (TVM). It emulates the TVM solver on the TI-83+ and TI-84 graphing calculators. Updated 6 November 2011 to work correctly when I% = 0.
Addition of three Vectors, and displays resultant Vectors. Can drag the endPoints of the three different Vectors, but the resultant always starts at the origin.
My pre-Calculus students were having trouble visualizing what it meant for a geometric series to converge. They understood the formula aspect and how to calculate the value of a convergent sum, and saw what it meant for numbers adding successively, but I
