The results can be summarised in this diagram: back to top The Sine Curve note: the sine graph starts atzero it repeats itself every360degrees y is never more than1or less than-1 a sin graph 'leads' a cos graph by 90 degrees back to top The Cosine Curve note: the cosine graph star...
The point on the unit circle is therefore the coordinate (cos(θ),sin(θ)cos(θ),sin(θ)cos(θ),sin(θ)): The yyy value of the coordinate on the unit circle gives us the value for tan(θ)tan(θ)tan(θ) so: At the point (1,0)(1,0)(1,0) we can say that ...

Note that the graph of tan has asymptotes (lines which the graph gets close to, but never crosses). These are the red lines (they aren't actually part of the graph). Also notice that the graphs of sin, cos and tan are periodic. This means that they repeat themselves. Therefore sin(...
