Calculator Programs 
TI84 


GSTATS  Graphical Stats
Make DotPlots, StemPlots, and Pie Charts. 

Stem plots are limited to a stem length of 10. Pie charts require summary data. 
GRAPH3D  Graphs multivariable functions f(x,y) 

Surface plot and a line plot(3D curve) shown. 
VECANAL  Vector analyisis functions 

Some useful calculations for Statics and Dynamics, and linear algebra. 
MULTINT  Multiple Integration 

Uses a GaussKronrod11 Quadrature. Triple integrals may take quite a while to produce a result. Accuracy of results vary. 
Riemann Calculate Riemann Sums 

Enter equation into Y1 and set the appropriate window before running the program. 
SLPFLD2  Calculates slope fields of the form f'(x,y) 


EIGSYS  Calculates Eigenvectors and eigenvalues and solves Initial Value Problems. 

Use any stored 2x2 matrix. 
EULER  use with SLPFLD2 to plot an approximate solution using Eulers Method 

Run SLPFLD2 to get a slope field. 
RK4  Uses the RungeKutta RK4 to approximate the solution to an IVP. 

Store y'(x,y) into Y1; run; and keep pressing ENTER for each successive point.
