Secant Formula Message #1 Posted by Matt Swanson on 2 Mar 2005, 7:21 p.m. I just bought a 33s how do you do a sec(angle) calculation sec=r/x? Any help from an old pro?

Re: Secant Formula Message #2 Posted by Thomas Okken on 2 Mar 2005, 7:25 p.m., in response to message #1 by Matt Swanson sec(x) = 1 / cos(x) cosec(x) = 1 / sin(x) cot(x) = 1 / tan(x) Hope this helps! - Thomas
