DISK #111     A Mathematics Theme Disk     This math disk is a collection ofthirty different math utili}        typrograms.  The subjects include curvefitting, statistical tests,distributions, matrix manipulations,geometry, some numb}        er theory, and someadvanced mathematics.    The disk includes an AUTORUN.SYSfile which displays a menu from whicheach pr}        ogram can be loaded by hittingthe "R" key, and then giving thenumber of the program desired.The option of returning to the}         menuhas been installed in these programs.For extensive use of a given programthis feature should be removed.     If the}         reset button is pressed orthe user enters bad data on INPUT, theprogram aborts as expected.  Theprogram can be run again,}         listed to aprinter or viewed on the screen at thistime.     On some printers the eighth bitmust be disabled to get prop}        eralphabetic characters.  For thestar/sg10 printer, this is done withchr$(27);"=".     All of the programs are highlysp}        ecialized.  Each requires the user tobring to the program an understandingof the meaning behind the utility, thetype of in}        put needed, and what isexpected as output.  In short, the diskshould be labeled "for mathematiciansonly".  For example, th}        e user needs toknow on exactly what criteria twosample populations are compared in theMann-Whitney test.  The input, thep}        rocess, and the output are eachmysterious to the non-user of thistest.     This disk was developed by WalterM. Lee of AU}        RA.  He realized that manypeople need specific, complex mathutilities, not just mathematicians.Although Atari is not known}         as anumber-cruncher, it can be used insolving many powerful algorithms.     So, when the need develops tosolve a system}         of six equations in sixunknowns, or you have a Mann-Whitneyattack, where do you turn? -- your MathBuster's disk, that's w}        here.Now, let's look at some of theseprograms.Number Theory and Algebra:  1. GCF - The Greatest Common Factor.You inpu}        t the two numbers and you getthe GCF.  2. PRIMEFAC.TOR - You input theinteger, you get the prime factors.Prime numbers ar}        e second class citizensin this program.  3. DETERMIN.3X3 - You input the 9elements of a 3x3 matrix and the valueof the de}        terminant is output.  4. MATRIXMU.LTI  5. MATRIXAD.DIT  6. MATRIXIN.VER - These threeprograms manipulate matricies bymul}        tiplication, addition, and inversionrespectively.  7. QUADRATI.CEQ - Input the threecoefficients of a quadratic equationa}        nd get out the expressions in thequadratic formula and the linearfactors.  8. POLYGONA.REA - If you input therectangular }        coordinates in order of theverticies, you get the area of thepolygon.  9. PERMUTAT.ION - This program givesyou the number}         of permutations andcombinations of n items taken r at atime.  10. INTERPOL.NOM - This is a searchfor the zeros of a fixe}        d polynomial.  Alittle alteration could let you useyour favorite polynomial.  12. DERIVATI.VE - Input x, outputf'(x). Sub}        titled: GUESS THE FUNCTION.  13. INTEGRGA.USS - The definiteintegral is calculated for the functionf=z^3 using Gauss's for}        mula.  14. GAUSSJOR.DAN - A system ofequations can be solved.  Allcoefficients and constants must beentered.  15. LINEPR}        OG.RAM - Linear programminguses the Simplex Method to answercomplex maximum or minimum problems.  16. POLYNOMR.OOT - Newto}        n's method ofcalculating zeros of a polynomialequation is used.  You input thecoefficients.  17. CHISQUAR.E - This progra}        m usesinput of the chi-square value and thedegrees of freedom.  A percentile isreturned which is most likely a numericrel}        iability of the chi-squarestatistic.  18. GEOMETRI.C - You provide thenumbers and get back the geometricmeans and deviati}        on.  19. FDRISTRIB.UT - This programcalculates percentile values for givenvalues on an f-distribution curve.  Youmust pro}        vide the value of f and thedegrees of freedom in the numerator anddenomerator.  20. BINOMIA.L - You give the numberof pla}        ys and the probability ofsuccess,  this program gives you theprobability of success in a givennumber of trials.   21. POI}        SSOND.IST - Using the PoissionDistribution, this program calculatesthe probability of an event occuring agiven number of t}        imes.  You must knowthe expected frequency of the event.  22. NORMALDI.ST - This programcalculates the probality and frequ}        encyof given values on a standard normaldistribution curve.  23. LREGRESS.ION - This program fitsa straight line to a giv}        en set ofcoordinates using the method of leastsquares.  Use to predict the y values.  24. CORRELAT.ION - This programcomp}        utes the coefficient of correlationbetween two variables. A linearrelationship is assumed between the twovariables.

The subjects include curvefitting, statistical tests,distributions, matrix manipulations,geometry, some nu`}        mber theory, and someadvanced mathematics.    The disk includes an AUTORUN.SYSfile which displays a menu from whicheach a}        program can be loaded by merelytyping a number. The option ofreturning to the menu has beeninstalled in these programs.  Fb}        orextensive use of a given program thisfeature should be removed.     If the reset button is pressed orthe user enters bc}        ad data on INPUT, theprogram aborts as expected.  Theprogram can be run again, listed to aprinter or viewed on the screen d}        at thistime.     On some printers the eighth bitmust be disabled to get properalphabetic characters.  For thestar/sg10 e}        printer, this is done withchr$(27);"=".     All of the programs are highlyspecialized.  Each requires the user tobring tf}        o the program an understandingof the meaning behind the utility, thetype of input needed, and what isexpected as output.  g}        In short, the diskshould be labeled "for mathematiciansonly".  For example, the user needs toknow on exactly what criteriah}         twosample populations are compared in theMann-Whitney test.  The input, theprocess, and the output are eachmysterious toi}         the non-user of thistest.     This disk was developed by WalterM. Lee of AURA.  He realized that manypeople need specifj}        ic, complex mathutilities, not just mathematicians.Although Atari is not known as anumber-cruncher, it can be used insolvk}        ing many powerful algorithms.     So, when the need develops tosolve a system of six equations in sixunknowns, or you havl}        e a Mann-Whitneyattack, where do you turn? -- your MathBuster's disk, that's where.Now, let's look at some of theseprogrm}        ams.Number Theory and Algebra:  1. GCF - The Greatest Common Factor.You input the two numbers and you getthe GCF.  2. Pn}        RIMEFAC.TOR - You input theinteger, you get the prime factors.Prime numbers are second class citizensin this program.  3.o}         DETERMIN.3X3 - You input the 9elements of a 3x3 matrix and the valueof the determinant is output.  4. MATRIXMU.LTI  5. Mp}        ATRIXAD.DIT  6. MATRIXIN.VER - These threeprograms manipulate matricies bymultiplication, addition, and inversionrespectiq}        vely.  7. QUADRATI.CEQ - Input the threecoefficients of a quadratic equationand get out the expressions in thequadratic fr}        ormula and the linearfactors.  8. TRIANGLE - A triangle has sixparts.  You input a proper set of threeand get back the ots}        her three. Remember:1 radian = about 57.3 deg.  9. POLYGONA.REA - If you input therectangular coordinates in order of thet}        verticies, you get the area of thepolygon.  10. PERMUTAT.ION - This program givesyou the number of permutations andcombinu}        ations of n items taken r at atime.  11. INTERPOL.NOM - This is a searchfor the zeros of a fixed polynomial.  Alittle altv}        eration could let you useyour favorite polynomial.  12. TRIGPOLY.NOM - Here a specifictrigometric polynomial is evaluated w}        atdomain values.  13.
