[libreoffice-users] Formula returns incorrect result

I'm trying to
calculate the Equation of Time (EoT) to determine the difference
between LAN (Local Apparent Noon) and GMT/UT-1  Greenwich Mean
Time.  Then I want to plot the EoT curve (a project for later, not
now)The following is the formula I use on my calculator.  The formula
gives a "close enough" EoT9.87xsin(2x360(3-81)÷365)-7.67 x sin(360(3-81)÷365+78.7)=
-4.584625249 (or.... -4 minutes 35.1 seconds...plus or minus)Calc doesn't give the same answer.  Here's the formula in calc;=9.87*SIN(RADIANS(2*360*(3-81)/365)-7.67*SIN(RADIANS(360*(3-81)/365+78.7)))The answer it returns is: -2.14883666659093Can you tell me what the correct layout of the format in calc is?Thank you,Peter
