DOS simulations for use with Precalculus I


Program Listings         Program Descriptions   Download Files


To run these simulations, you must have them on your hard drive or on a floppy.  

The programs may be obtained by downloading (just click on the name of the program under DOWNLOAD FILES, below).  This is the easiest way to get them.  Your computer will tell you where it wants to save the file (usually on the Desktop).  You can save it in another folder or directory if you wish, and you can even give it a different name.  In any case, remember where it is.

If the program is on the Desktop, just double-click it to run it.  Otherwise use the Run option and run the program.

To obtain the programs from the VHCC LAN.  You must be in the math/physics directories (when the computer boots, it will either boot into this drive or it will give you the choice).  The programs are on the E: drive.  They are copied with the DOS command   

        copy ***********  b:

where b: is the name of the drive in which you place your diskette and ****** is the full name of the program, including the .exe on the end.

Copy these programs from your floppy diskette to a c:\vhmthphy directory or folder you create on your computer.  You need not use this folder name, but these directions will assume that you do.

To run a program from the DOS window, simple type the command      

c:\vhmthphy\*******

at the DOS prompt and the program will run.  If you have trouble stopping the program, try hitting the s or the q key (for 'stop' or 'quit').  If this doesn't work, hold down the Ctrl key and hit the pause/break key.

Program Descriptions

TIMER

General-purpose timer.  Gives time since first strike of 't' key, time interval since last strike.  Also with graphing and filing options.

RNDMLNS

Estimating ratios and proportions of line lengths, areas and volumes of geometric figures.

SIMULEQ

Solving simultaneous equations in the context of fitting a quadratic function to 3 points.  Program poses randomized problem, prompts user for next step, shows next step.

QUADEQ

The mechanics of solving quadratic equations and interpretation of results in terms of the graph of the corresponding quadratic function.

BASICGPH

The process of finding the parameters a, b and c of the quadratic function y = ax^2 + bx + c which models a given parabola.  Randomized parabolas, step-by-step explanation of the solution.

FKNNOTAT

Examples of function notation.

RNDPROP

Randomized problems on proportionality, primarily on geometric proportionalities.  First 8 problems with detailed solutions.  Other problems with briefer solutions.

EXPINTR

Random problems with detailed solutions for compound interest, radioactive decay, and other situations involving exponential functions.
