Trigonometry

How do you do the trigonometry funtions of cosine & sine.

Type into calculator entry bar: plot(sin(x),x=-180..180, -1.0..1.0)
or cos instead of sin or change domain by adjusting 180 to smaller or larger degrees;
adjust range by making -1 to 1 smaller or larger;
adjust to radians by selecting radian button at base of calculator and then adjust domain to suit

Hope that helps
