MS Office Forum / Excel / New Users / March 2008SIN(90)
If I use a calculator to compute sin 90¢X, the answer should be 1. When I enter the formula =SIN(90) in Excel, the anwser is 0.894. How can I get the answer of sin 90¢X in Excel? Thanks in advance~~ It works on radians so you have to convert =SIN(RADIANS(90))  Signature--- HTH Bob (there's no email, no snail mail, but somewhere should be gmail in my addy) > If I use a calculator to compute sin 90¢X, the answer should be 1. > When I enter the formula =SIN(90) in Excel, the anwser is 0.894. > How can I get the answer of sin 90¢X in Excel? > Thanks in advance~~ Thank you very much!!

Radian is the SI standard. Degrees/minutes/seconds are 'outside the SI' and I haven't seen 'grads' used for a while. Units are everything ... so assume them at your peril. ... and do read the help - sometimes it helps. :) > >>A quick check of Excel help reveals: > >> [quoted text clipped - 10 lines] > Units are everything ... so assume them at your peril. ... and do read the > help - sometimes it helps. :) can i ask you something? how can i convert radians into grads??? There are 2*Pi radians in a circle. There are 400 Grads in a circle. There are 360 degrees in a circle. so if A1 contains radians, then =400*a1/(2*pi()) will return the number of grads. <<snipped>> > can i ask you something? how can i convert radians into grads??? SignatureDave Peterson 1 radian = 63.66198 grads 1 grad = 0.01570796 radians. You do the math.

I can do better than that ... here is a GREAT site that can convert anything to anything : Convertit.com If there's something it can't convert, I haven't found it yet. I tested it on the 'methuselah' (sp ?) ... no problems. :) Enjoy. Paul Hyett <vidcap...@invalid83261.co.uk> wrote... ... >Who uses radians rather than degrees, anyway? Bricklin and Frankston did in VisiCalc, and that set the base standard for all spreadsheets since. Backwards compatibility is a wonderful thing, ain't it? >> A quick check of Excel help reveals: >> [quoted text clipped - 5 lines] > > Who uses radians rather than degrees, anyway? A mathematician would use radians as it is the natural unit to use for differentiation, power series etc. Who apart from a mathematician would use SIN? Maybe biblical scholars. Let he who is without SIN cast the first stone. I guess no one threw any stones, so everyone had some SIN. (But I may be wrong...) > >> A quick check of Excel help reveals: > >> [quoted text clipped - 10 lines] > > Who apart from a mathematician would use SIN? SignatureDave Peterson Not really... if "he" is **without** "SIN", then it doesn't matter if SIN uses radians or not.<g> Rick > Maybe biblical scholars. > [quoted text clipped - 18 lines] >> >> Who apart from a mathematician would use SIN? peccavi - General Charles Napier Signature--- HTH Bob (there's no email, no snail mail, but somewhere should be gmail in my addy) > Maybe biblical scholars. > [quoted text clipped - 18 lines] >> >> Who apart from a mathematician would use SIN?
