[. . . ] (ValueNposInteger+1) nPr(Value, nonInteger) nPr(List1, List2) ⇒ Value!/ (ValueNnonInteger)! ⇒ list Returns a list of permutations based on the corresponding element pairs in the two lists. The arguments must be the same size list. TI-Nspire™ Reference Guide 69 nPr() nPr(Matrix1, Matrix2) Catalog > ⇒ matrix Returns a matrix of permutations based on the corresponding element pairs in the two matrices. npv() npv(InterestRate, CFO, CFList[, CFFreq]) Catalog > Financial function that calculates net present value; the sum of the present values for the cash inflows and outflows. InterestRate is the rate by which to discount the cash flows (the cost of money) over one period. CFList is a list of cash flow amounts after the initial cash flow CF0. CFFreq is a list in which each element specifies the frequency of occurrence for a grouped (consecutive) cash flow amount, which is the corresponding element of CFList. The default is 1; if you enter values, they must be positive integers < 10, 000. nSolve() nSolve(Equation, Var[=Guess]) Catalog > ⇒ number or error_string nSolve(Equation, Var[=Guess], lowBound) ⇒ number or error_string ⇒ number or error_string ⇒ number or error_string nSolve(Equation, Var[=Guess], lowBound, upBound) nSolve(Equation, Var[=Guess]) | lowBound<Var<upBound Note: If there are multiple solutions, you can use a guess to Iteratively searches for one approximate real numeric solution to Equation for its one variable. Specify the variable as: variable – or – variable = real number For example, x is valid and so is x=3. nSolve() attempts to determine either one point where the residual is zero or two relatively close points where the residual has opposite signs and the magnitude of the residual is not excessive. If there are no more pending Try. . . Else. . . EndTry error handlers, the error dialog box will be displayed as normal. Note: See also ClrErr, page 17, and Try, page 105. Note for entering the example: In the Calculator application on the handheld, you can enter multi-line definitions by pressing @ at the end of each line. piecewise() piecewise(Expr1 [, Cond1 [, Expr2 [, Cond2 [, … ]]]]) · Catalog > Returns definitions for a piecewise function in the form of a list. You can also create piecewise definitions by using a template. Note: See also Piecewise template, page 2. poissCdf() poissCdf(l, lowBound, upBound) ⇒ number if lowBound and upBound are numbers, list if lowBound and upBound are lists poissCdf(l, upBound) for P(0{X{upBound) upBound is a number, list if upBound is a list Catalog > ⇒ number if Computes a cumulative probability for the discrete Poisson distribution with specified mean l. For P(X { upBound), set lowBound=0 poissPdf() poissPdf(l, XVal) a list Catalog > ⇒ number if XVal is a number, list if XVal is Computes a probability for the discrete Poisson distribution with the specified mean l. TI-Nspire™ Reference Guide 73 4Polar Vector 4Polar Note: You can insert this operator from the computer keyboard by typing @>Polar. Catalog > Displays vector in polar form [r ±q]. The vector must be of dimension 2 and can be a row or a column. Note: 4Polar is a display-format instruction, not a conversion function. You can use it only at the end of an entry line, and it does not update ans. Note: See also 4Rect, page 81. complexValue 4Polar Displays complexVector in polar form. Radian angle mode returns reiq. In Radian angle mode: complexValue can have any complex form. However, an reiq entry causes an error in Degree angle mode. Note: You must use the parentheses for an (r±q) polar entry. In Gradian angle mode: In Degree angle mode: polyEval() polyEval(List1, Expr1) ⇒ expression polyEval(List1, List2) ⇒ expression Catalog > Interprets the first argument as the coefficient of a descending-degree polynomial, and returns the polynomial evaluated for the value of the second argument. polyRoots() Catalog > ⇒ list polyRoots(ListOfCoeffs) ⇒ list polyRoots(Poly, Var) The first syntax, polyRoots(Poly, Var), returns a list of real roots of polynomial Poly with respect to variable Var. Do not use unexpanded forms such as y2·y+1 or x·x+2·x+1 The second syntax, polyRoots(ListOfCoeffs), returns a list of real roots for the coefficients in ListOfCoeffs.

To allow complex results, change the “Real or Complex” Mode Setting to RECTANGULAR or POLAR. Invalid bounds No sign change Argument cannot be a list or matrix Argument error The first argument must be a polynomial expression in the second argument. [. . . ]
