Homework Statement
cosθ = 1.316581
Homework Equations
cos-1cosθ = θ // if and only if 0[itex]\leqθ\leq1[/itex]
The Attempt at a Solution
This problem is actually the result of an attempt at a solution to solve an even larger problem (SAS triangle specifically). I need to know how to restrict the cosθ value in order to get θ. If it helps any, the original fraction was (49-196.457081)/-112
I know its got to be simple. I just have a terrible professor for math :P
