ASN Arc SiNe

Function

ASN calculates the value of an angle from its sine.

How to use ASN

ASN is followed by a numeric value. An expression must be enclosed in brackets, for example

60 LET x=ASN (y*z)

The value following ASN (y*z above) is the sine of the required angle and it may range from -1 to 1. ASN then returns the value of the angle in radians. To convert radians to degrees, multiply the value returned by ASN by 180/PI.

Example

The command

PRINT 180/PI * ACS 0.5

display 30, the angle in degress that has a sine of 0.5.

Format

  • ASN num-const
  • ASN num-var
  • ASN (num-expr)
