The experiments range from simple momentof inertia concepts to the testing of more complex friction models and may be easily modified tovary the results. The disk is an appropriate system for sophomore level students to analyze, sincethe solution of its angular momentum differential equation results in a simple angulardisplacement versus time relationship, q(t), even though the frictional model is non-linear,varying with the angular velocity w raised to some unknown power. This permits superior resultssince the q vs. t data set can be accurately determined over the range of angular velocities usingan ordinary

) from Cartesiancoordinates to spherical coordinates the result would be (R R + 0 q + 0 f). This was the correctresult but upon going back from spherical to Cartesian a large complicated expression resulted.Upon close examination, it was seen that the answer was correct but was not in its simplest form.In order to compensate, some of the expressions used in the conversion process were pre-simplified before they were programmed. It must be noted that the program does not alwayssimplify expressions to their simplest form. This is especially true when converting fromspherical to Cartesian coordinates or from cylindrical to Cartesi an coordinates.

Since the resistance of a resistor increases withtemperature, let’s assume that the resistor is heated so the resistance at time t is R (t ) = 1 + t 10ohms. Let’s also assume that L = 0,1 henrys, C = 2

We had to reevaluate our thinking process and convert the code block by block. The conversion of an idea was much easier to implement than converting a line of code. Once we understood the methodology behind a chunk of code, it was relatively straightforward to express that idea in Mathematica’s syntax…. The reason why this process was straightforward was due to our knowledge of Mathematica on an intermediate level.”q “The Maple code was not very helpful as a template.

correlation between any pair of the output and the input random variablescan also be established. For example between any pair of input random variables, thestatistical correlation is: r pq ( X p , X q ) = cov( X p , X q ) VarX p .VarYq (1.10)where, cov(X p,Xq) is equal to the covariance function between the pair of the randomvariables X p and X q, where p¹q. When the cov(X p,Xq) becomes cov(Xp,Xq)=VarX p =VarXq , therefore the statistical correlation becomes r pq ( X p , X q ) = 1.0Statistical correlation is the degree of linear correlation between the pair of the randomvariables X p and X q. Perfect correlation therefore means that there is a linear relationshipbetween the pairs of random variables. This can only occur when the
