[libreoffice-users] Fwd: Formula returns incorrect result


No idea how this
gibberish got returned
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
