First, some basic trig(onometry) background so we all are on the same page. Trig derives from very old triangle work dating back 2500 years or so. ...
I knew I should have put some graphics in the previous post's discussion. I can't recall now who the instructor was this far removed but, when I we...
Some comments to the previous posts - [color=blue]the parallel lines example is linked up to the vertical scale[/color] That's just a consequenc...

[color=blue]the graph's aren't 10mm apart, so skewing the ruler doesn't fit the box.[/color] You're missing the point, I fear. The idea of the s...
