I apologize. I forgot that asin worked in radians. Also, I made my own code to return the correct inverse sin based on the waves upward/downward trend (below).

Thank you,

Mr. Israel

def invSin(number,up):
  result=asin(number) 
  if(up==0): # negative trend correction  
    if(result<0):
      result=-pi-result # -halfPi -(halfPi+result)
    if(result>0):
      result=pi-result # halfPi + (halfPi-result) 
  return result
