The Trig model (#4080) and Desktop (#44080) calculators have
standard trigonometric keys, in addition to right triangle/rafter keys
(e.g., Rise, Run, Diagonal), for advanced right triangle mathematics.
The Sine, Cosine and Tangent of an angle are defined in relation to
the sides of a right triangle.
Using the Ç key with the trigonometric function displays the
inverse (Arcsine, Arccosine, and Arctangent). These are used to find
the angle for the Sine, Cosine, or Tangent value entered.
