I need a little refresher here. Left Highscool 20 years ago...
I want to find an angle (Sin). I remember that Sin = Oposite / Hypo. Oposite is 2" and the Hypothenuse is 22.1".
What I can't remember is how to do the calculation on the Calculator... Do I input 2 / 22.1 then equals then Sin function or I do 2 / 22.1 then Sin Function???
Welcome to sciforums....
I have always had troubles remembering that exactly too, but here's the answer to your question:
(i have a nice trick to remember, but that's based on dutch, so you don't need it :))
sinus equals oposite/hypo
when we calculate: 2/22.1 = 0,0905
this is the sinus of the angle you need, to obtain the real angle you have to take the inverse sinus of it, which will give the following answer:
(I don't know which is standard in the US.....but with radian you must be able to find out, and with the 'inverse sinus answer' you can calculate it yourself :))
(btw, where is the calculation about?)

I'm building "Camber Plates" to adjust Front Camber on my Car.
I need to know how much I need of adjustment in order to be able to adjust Camber Properly.
I'm using the Calculator that comes with Win98. How do I "plug in" the numbers to get the "inverse sinus".
Sorry about the Basic question but I'm totally mentally stuck...

Ok. I got it.
Tx for the ansewer. Were are you located??? I'm in Trenton Ontario Canada.
Wonder if the mnemonic SOH_CAH_TOA, pronounced as a Native
American sounding word 'sohcahtoa' would be of any help?
Sin = Opposite / Hypotenuse
Cos = Adjacent / Hypotenuse
Tan = Opposite / Adjacent
Take care, and welcome to Sciforums :)

Yes. That is how I remember the Formulas. The problem was that I did not remember how to do it with the Calculator...
You guys were a greath help.
hehe, rather similar to the dutch based word:
(in my math school-book illustrated with a ship called s.o.s. Castoa going down with a certain angle....it is amazing how NOT funny educationers can be)
oh and, I am from The netherlands, but this is more meant to be in PM's ;)
