ASIN(x)

• Where x is the number and it is varying from -1 to 1.
• The value of ASIN(x) is in radians.
• Calci returns the arcsine (inverse sine) of a number. Output is the angle in Radians.
• The number can be a single value or any number of values.
• To convert arcsine to degrees, multiply it by 180/PI.

For example, ASIN(0.5,(-0.2),1) gives the arcsine or inversesine values for each element.

Description

ASIN(n)

Consider n = (-0.8) then, ASIN((-0.8)) is -0.9273

• This function is the Inverse function of Sin in trigonometry.
• It's also called as Cyclometric function.
• ASIN is described as Arcsin and denoted by $sin^{-1}$(x).
• In ASIN(X) ,x value should be with in -1 & 1.
• ASIN function determines the arcsine of the given number.

Here x is in Radians. To convert a degree value to radian, multiply 'x' with PI()/180 or use the Radians function RADIANS(X)

To find the angle in degrees, multiply the result angle with 180/PI. DEGREES function can also be used.
For example ASIN(-0.8)*180/PI() or DEGREES(ASIN(-0.8)) gives -53.13010235415598

Examples

ASIN(N)	Value
ASIN(-0.8)	-0.9273
ASIN(1)	1.5707963267948965
ASIN(0.559)	0.5931792803038736
