I use the Sharp EL-531WH calculator. I currently doing trigonometry as a maths subject, and I would like to know what's the calculator formula for finding out the degrees of a fraction that has a square root in it?
Eg. Sin ?= ?3 / 2 [ where 3 is over 2 ]
Tan ?= ?3
Cos ?= ?5 + 1 / 4 [ where 1 is over 4, not a quarter ]
It's not homework, but typing up the formula of this usually ends up saying 'Error 2' or anything similar to that.
