I have calculated sine for an angle based on the opposite side being 4.5 and the hypotenuse being 11.75. How do I use the calculator to tell me the degrees in the angle?
+37155 First....look in the Lower Left corner to make sure the calculator is set to ' deg'
then sin = opp/hyp = 4.5/11.75 = .382978
The press the ' 2nd ' key on the calculator then the ' asin ' key ....which is arc sin which is sin inverse...
= 22.52 degrees
Thanks! never used one of these before. 30 years ago we relyied on tables.
+2511 EP, why did you use a slide rule? Scientific Calculators were very common and cheap then, and a few of the programmable calculators cost about the same as an expensive text book.
Did you go to an Amish school?

“It was a conspiracy; I tell you … A real conspiracy! But they couldn’t take my slide rule away from me. No sir! I was smart – I hid it in my sock. Pretty sneaky, wasn’t it?”
ROFL!!
I have a slide rule, but I do not know how to use it.
