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)2,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
