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)
