cos(9.47/12) = 0.70. Maybe you slipped on the keyboard and hit 4 instead of 1 accidently?

cos(9.17/12) = 0.721959221055 (Casio CFX-9850GB PLUS). Display shows 0.7219592211. cos(9.17/12) = 0.72195922106 (Casio FX-602P). Display shows 0.721959221. cos(9.17/12) = 0.721959221055309 (OpenOffice.org Calc 2.1) cos(9.17/12) = 0,72195922105530939890728569812481 (Advanced calculator in Windows XP) cos(9.17/12)= 0,70 seems to be wrong. The answer of a cosinus calculation is not in degrees or radians. The parameter is, however. In this case: cos(9.17/12 [rad]) = -> cos(9.17/12・180/π [°]) = cos(43.78°) = 0.72. Besides, it seems like you try to convert radians to degrees by multiplying the radians with 360/π, which instead should be 180/π, but that's another story. Hope this helps. I don't really understand what you could be doing wrong, that gives you 0.70 instead of 0.72, but as far as I tested, OpenOffice.org seems to give the correct answer, at least for cosinus. I guess that you with "tanus" mean "tangens" (which seems to be "tangent" in English, according to what I found with google) or is it really "tanus" in your language? Sinus, cosinus and tangens is Latin (I think) and seems to be the same in German, Swedish, Italian etc, but not in English (sine, cosine, tangent?), but again, quite another story… Johnny Andersson 2007/3/2, lilian van emden <[EMAIL PROTECTED]>: > > hello , I use openoffice a lot but there is a very irritating error > if you use the sinus/ cosinus ( and maybe also the tanus) function they > give different value as answer (compare with my calculator, the calculator > on two different computers), so I guess, somethings wrong with open office > > greetings lilian > > dutch version: > > goeden dag , ik heb gemerkt dat de sinus en cosinus functie onder open > office andere waardes aangeven dan bv mijn rekenmachine , de rekenmachine > onder linux en windows, het scheelt nog al veel en is behoorlijk vervelend, > ik hoop dat deze fout opgelost kan worden > > > met vriendelijke groeten lilian > > cos (9.17/12)=0.70(others) or 0.72(open office) ->80.30 degrees (others) > or 82.72 degrees (open office) > > > Stop the Forest Service from killing more wolves, bears, cougars, and > other animals in the wild: > http://go.care2.com/99055 > > http://www.Care2.com Free e-mail. 100MB storage.
