JimmyPageZoSo56 Posted May 23, 2008 Share Posted May 23, 2008 For extra credit for my Trig. class, I need to explain why sine divided cosine always equals tangent. Does somebody know for sure so I can double check my work? I have a pretty good idea why, but I am not 100% sure. This is what I have: SOH-CAH-TOA Sin = opposite/hypotenuse Cos = adjacent/hypotenuse Tan= opposite/adjacent So, (O/H) divided by (A/H) = O/A because the H cancels out. If you can help, that'll be great! It will be much appreciated. Link to comment Share on other sites More sharing options...
