Sometimes when you are wanting to illustrate a process or to compose a test or exam question it would be handy to have a way of generating a set of numbers (observations) which conform to the distribution of a specific random variable. This apLet is designed to simulate data sets for various common random variables.
The user can generate data on any of the eight common r.v.'s shown in the screen shots left. Most of the simulations are fairly quick but the Binomial and Pascal simulations are a little slow. Time estimates are given for these two before the simulation process begins. Due to the memory limitations on the calculator, only a limited number of observations can be stored.

Sine Define
This aplet visually illustrates the production of graphs for sine, cosine and tangent using the Unit Circle. The graph is gradually traced out on the axes provided, while the angle progressively moves around the circumference of the Unit Circle.
