Need help with Natural Log

Recommended Posts

I need help with these 3 formulas. Since PHP doesn't accept the LN function. I appreciate the help.

 

              1.162*ln('PREBUN'/'POSTBUN') 
 

              -ln(('POSTBUN'/'PREBUN)-(0.008*('TIME'/60)))+((4-(3.5*'POSTBUN'/'PREBUN'))*'UFVOL'/'POSTWEIGHT')

 

              ln('PREBUN'/'POSTBUN')

Thanks for the most obvious non helpful comment. I know it's a log function but, I'm having an issue trying to convert it to log that's why I'm asking for help in the "PHP Coding Help" forum.

Then it would probably work better if you had said something like "how do I translate the below equations into PHP code" instead of "PHP doesn't have a ln function so what do I do".

What are PREBUN and POSTBUN and TIME and all those? Do you already have them set up as variables?
