Hello. 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??? Ghislain.
sinus -1 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 Please Register or Log in to view the hidden image!) 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: in degrees: 5.192242205 in radian: 0.0904977376 (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 Please Register or Log in to view the hidden image!) SPACE YA! (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... Ghislain.
Ghislain ... 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 Please Register or Log in to view the hidden image!
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. Tx again. Ghislain.
hehe, rather similar to the dutch based word: s.o.s. Castoa (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 Please Register or Log in to view the hidden image!
