As I stated in an earlier post, I'm new at this.
I'm trying to write a procedure to calculate what is called a "crescent latitude". The full formula can be seen here: https://db.tt/QAUzH5i0.
b is equal to 0.081819221; it takes a single parameter φ (latitude of a location in degrees)
I normally get errors like unable to parse, unable to match delimters, etc. and the result is the name of the procedure and whatevere value of the parameter I put in parenthesis, not the calculated value.
Anybody can help?
