How to find maximum for 2 variable function

[MySchizoBuddy]

My elevation function depends of day of year (d) and decimal hours of the day(hrs)

I want to find Solar Noon the point of highest elevation angle.

I have done it for just one day of the year. But i want it to be able to calculate solar noon for any day of the year. I want it to be a variable of d as well
