SIN

Purpose:

Calculates the sine of any expression.

SIN(val)

val

A scalar, series or table.

A scalar, series, or table.

sin(-2*pi..pi/100..2*pi);gridhv;griddot

$image\sinpic01.gif$

displays the sine from -2π to 2π.

sin(pi/2)

returns 1.

sin(-2..0.1..2)

returns a 41 point series.

t = 0..0.01..1

sin(2*pi*10*t)

returns a 101 point series of a 10 Hertz sinewave sampled at 100 samples per second. This is equivalent to:

gsin(101, 0.01, 10)

The sine is defined as:

for all complex z.

The function calculates in radians unless degrees are specified with the SETDEGREE function.
