# Creation of a Function

I am trying to create two functions but I am having trouble. The first consists of converting degrees Fahrenheit to Kelvin 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 Fahrenheit 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.

Thanks, L

• Probably N15 is the number of chirps produced in 15 seconds (from Wikipedia article), so chirping rate is rate[Tf_] := (Tf - 40)/15. – Alx Sep 11 at 14:12
• I am just having trouble with the second function. Oh go on, don't leave us guessing, tell us what trouble your are having ... – High Performance Mark Sep 11 at 16:07

chirpsToTemp[n_]:=n+40

toKelvin[f_]:=((f-32)*(5/9))+273
