Using mathematical functions 13-7

TAYLOR Calculates the nth order Taylor polynomial of expression

at the point where the given variable = 0.

TAYLOR (expression, variable, n)

Example

TAYLOR(1 + sin(s1)

,s1,5)with Radians

angle measure and Fraction number format (set in

MODES) returns 1+s1^2-1/3*s1^4.

Complex number functions

These functions are for complex numbers only. You can

also use complex numbers with all trigonometric and

hyperbolic functions, and with some real-number and

keyboard functions. Enter complex numbers in the form

(x,y), where x is the real part and y is the imaginary part.

ARG Argument. Finds the angle defined by a complex number.

Inputs and outputs use the current angle format set in

Modes.

ARG((x, y))

Example

ARG((3,3)) returns 45 (Degrees mode)

CONJ Complex conjugate. Conjugation is the negation (sign

reversal) of the imaginary part of a complex number.

CONJ((x, y))

Example

CONJ((3,4)) returns (3,-4)

IM Imaginary part, y, of a complex number, (x, y).

IM ((x, y))

Example

IM((3,4)) returns 4

RE Real part x, of a complex number, (x, y).

RE((x, y))

Example

RE((3,4)) returns 3
