I am trying to create two functions but I am having trouble. The first consists of converting degrees farenheit to Kelving using this formula (F - 32)*(5/9) + 273 and another calculates the cricket chirping rate (in s^-1) using Dolbear's law which is Tf=40+N15 where Tf is the temperature in degrees Farenheit and N15 is the rate of chirps per minute.
I was able to make the temperature function.
f[F_] = (F - 32)*(5/9) + 273
I am just having trouble with the second function.
