Example 1. Example of the cosinv opcode.

/* cosinv.orc */
/* Written by Kevin Conder */
; Initialize the global variables.
sr = 44100
kr = 4410
ksmps = 10
nchnls = 1

; Instrument #1.
instr 1
  irad = 0.5
  i1 = cosinv(irad)

  print i1
endin
/* cosinv.orc */
        
/* cosinv.sco */
/* Written by Kevin Conder */
; Play Instrument #1 for one second.
i 1 0 1
e
/* cosinv.sco */
        
Its output should include lines like this:
instr 1:  i1 = 1.047
