Try to code a formula for predicted oxygen cosumption:

o2 consumption equals:

BSA x (138.1 - 17.04 x e{subscipt}log(age) + 0.378 x HR)

BSA is body surface area stored in E17
HR is heart rate stored in G23
Age is stored in F17

I can get everything but the log part. The constant "e" followed by a
subscript "log" followed by a normal script (age)

Any help would be appreciated...
