POLYROOTS TI NSPIRE UPDATE

Interprets the first argument as the coefficient of a descending-degree polynomial, and returns the polynomial evaluated for the value of the second argument. This is because the degree can be extracted without expanding the polynomial. The degree can be extracted even though the coefficients cannot. If you omit Var, the polyDegree() function selects a default from the variables contained in the polynomial Poly. Returns the degree of polynomial expression Poly with respect to variable Var. We recommend that you do not omit Var unless Poly is an expression in a single variable.Įxpands the polynomial and selects x for the omitted Var.

Poly must be a polynomial expression in Var. Returns a list of the coefficients of polynomial Poly with respect to variable Var. Note: You must use the parentheses for an (r ∠θ) polar entry. However, an re i θ entry causes an error in Degree angle mode.

You can use it only at the end of an entry line, and it does not update ans.ĬomplexValue can have any complex form. Note: ► Polar is a display-format instruction, not a conversion function. The vector must be of dimension 2 and can be a row or a column. Note: You can insert this operator from the computer keyboard by typing vector in polar form. PoissPdf( λ, XVal) ⇒ number if XVal is a number, list if XVal is a listĬomputes a probability for the discrete Poisson distribution with the specified mean λ. PoissCdf( λ, upBound) for P(0 ≤ X ≤ upBound ) ⇒ number if upBound is a number, list if upBound is a listĬomputes a cumulative probability for the discrete Poisson distribution with specified mean λ. PoissCdf( λ, lowBound, upBound) ⇒ number if lowBound and upBound are numbers, list if lowBound and upBound are lists You can also create piecewise definitions by using a template. Returns definitions for a piecewise function in the form of a list. Note for entering the example: For instructions on entering multi-line program and function definitions, refer to the Calculator section of your product guidebook.įor an example of PassErr, See Example 2 under the Try command, here. Note: See also ClrErr, here, and Try, here. If there are no more pending error handlers, the error dialog box will be displayed as normal. If what to do with the error is not known, use PassErr to send it to the next error handler. If the error is to be processed or ignored, use ClrErr. The Else clause of the block should use ClrErr or PassErr. If system variable errCode is zero, PassErr does not do anything. If the argument is an expression, you can use °, G, or r to override the angle mode setting temporarily. Note: The θ argument is interpreted as either a degree, radian or gradian angle, according to the current angle mode. Returns the equivalent y-coordinate of the (r, θ) pair. Note: You can insert this function from the computer keyboard by typing ). Note: The θ argument is interpreted as either a degree, gradian or radian angle, according to the current angle mode. Returns the equivalent x-coordinate of the (r, θ) pair. You are here: TI‑Nspire™ CX CAS Reference Guide > Alphabetical Listing > P P
