Selected TI83 Functions - Syntax
  1. binomcdf(numtrials,p,x) - binomomial probability cumulative distribution function,
    numtrials = number of trials,
    p = probability of success, and
    x is the number of successes.
    It is equivalent to P(X<x), where P is the binomial probability distribution function P(x)=C(N,x)px(1-p)N-x
  2. binompdf(numtrials,p,x) - binomomial probability distribution function,
    numtrials = number of trials,
    p = probability of success, and
    x is the number of successes.
    It is equivalent to P(X=x), where P is the binomial probability distribution function P(x)=C(N,x)px(1-p)N-x
  3. value->Frac - convert value into a fraction

  4. LinReg(ax+b) Xlist, Ylist - Linear Regression
    Xlist is a list of x - coordinate
    Ylist is a list of y - coordinate
    This function returns with the values of a (slope) and b (intercept) of the regression line.
  5. valueA nCr valueB - Combinatorial function
    returns the number of combinations of valueA objects, taken valueB at a time
    that is, C(valueA,valueB), where C(N,x) = N!/((N-r)!r!)
  6. valueA nPr valueB - Permutation function
    returns the number of permutations of valueA objects, taken valueB at a time
    that is, P(valueA,valueB), where P(N,x) = N!/(N-x)!
  7. InvNorm(area,mu,sigma - Normal area function
    area = area enclosed,
    mu = mean of the distribution, and
    sigma = standard deviation of the distribution .
    It returns x, where P(X < x)=area
  8. normalcdf(a,b,mu,sigma) - normal probability cumulative distribution function,
    a = lower bound,
    b = upper bound,
    mu = mean of the distribution, and
    sigma = standard deviation of the distribution .
    It is equivalent to P(a < X < b), where P is the normal probability distribution function P(x)=1/(sigma sqrt(pi)) e-(x-mu)22sigma2
  9. normalpdf(numtrials,p,x) - normal probability distribution function,
    numtrials = number of trials,
    p = probability of success, and
    x is the number of successes.
    where P is the normal probability distribution function P(x)=1/(sigma sqrt(pi)) e-(x-mu)2/2sigma2
  10. *row(value,matrix,row) - matrix row multiplication
    value = value multiplied by,
    matrix = matrix, and
    row = row number
  11. *row+(value,matrix,rowA,rowB) - matrix row multiply/add
    value = value rowA is multiplied by, then added to rowB,
    matrix = matrix, and
    rowA = row number A rowB = row number B
  12. rref(matrix) - row reduced echelon form
    matrix = matrix
  13. SetUpEditor - resets List Editor.
    Removes all list names from the stat list editor, then restores list names L1, L2, ..., L6 to columns 1 ... 6.
  14. 1-Var Stats XList, FreqList
    Xlist - data list,
    FreqList - list of frequencies,
