Sin ( double angle);

Default values:


Returns the trigonometric sine of an angle.

Input parameters

Parameter Default value Description
angle - Defines angle (in radians) whose sine is calculated.


declare lower;
input a = 0;
input b = 10;
input periodBars = 20;
def w = 2 * Double.Pi / periodBars;
def x = CompoundValue(1, x[1] + 1, 0);
plot F = a + b * Sin(w * x);

The code draws the sine function depending on the variable which starts from one and increments by one on each bar. The cyclic frequency(w) is calculated based on the periodBars constant.
