Converting line slopes to angles

  1. Feb 17, 2005 #1
    Hi! I'm examining the equality between line slopes and angles. I've, using trig, conclude that this equation holds:
    [tex]sin(v) = \frac{m}{ \sqrt{1+m^2}}[/tex]
    Anyone knowing a simpler equation is very welcome to post.

    [tex]\tan{\alpha} = m[/tex].
