Additionally(take that Ben) if you cant figure out the answer, sometimes, you can prove that there is no answer!

I only went to Algebra 2 and then I was on to better things, like an extra PE period and photojournalism. Oh yeah, and I ended up being a sophomore in college my senior year in high school because I took college courses at the local magnet center. Math frightens me, but I do like the fact that there is ALWAYS a right answer. Candace K.

I use the table to figure out how tall things are. height of object = tan(angle) * distance from object I always amaze people who forgot all their high school trig.

In CF, it's returned in radians (as it should be!). To convert radians to degrees, simply multiply by 180/pi. So, in your example, the angle A in degrees would be 180/pi*arcsin(x/z) or 180/pi*arccos(y/z) or 180/pi*arctan(x/y) which (should) all come out to be about 63.4 degrees. did that help? --Ben Doom Programmer & General Lackey Moonbow Software : -----Original Message----- : From: Haggerty, Mike [mailto:[EMAIL PROTECTED]] : Sent: Monday, December 30, 2002 3:35 PM : To: CF-Community : Subject: RE: Geometry Question : : : Oh dear, I must be a little worse off than I thought. : : Taking a look at what you wrote has yielded little to me.
