ASIN

Description: Returns the arcsine, or inverse sine, of a number. The arcsine is the angle whose sine is Number. The returned angle is given in radians in the range -pi/2 to pi/2.

Syntax: ASIN(Number)

• Number is the sine of the angle you want and must be from -1 to 1.

Remarks:

• To express the arcsine in degrees, multiply the result by 180/PI or use the DEGREES function.

• When used in a RENO flowchart, Number must evaluate to a numerical value. It can include:

Example:

• ASIN(-0.5) = -0.5236 [the arcsine of -0.5 in radians, -pi/6]

• ASIN(-0.5)*180/PI() = -30 [the arcsine of -0.5 in degrees]

• DEGREES(ASIN(-0.5)) = -30 [the arcsine of -0.5 in degrees]
