Hello I am trying to convert a written formula into Excel but not having much joy! Please see below, is there anything obvious that I am missing? =(F$2/sq(F$3^2+10^4*pi^2*F$4^2))*sin(100*pi*A2-tan^-1(100*pi*F$4/F$3)) Your help would be greatly received :)

In an excel work book I have a (large number of) dynamic formula linked to Pi, vlookup and standard calculation formulas in another worksheet(s). Using the calculation options in the formulas menu I can update all the worksheets individually except the sheet that contains the dynamic links (approximately 600). Excel crashes at this point. How do I get this tab to calculate without crashing?
