The
Desktop and Trig Plus III calculators have standard trigonometric
keys, in addition to Right Triangle/Rafter keys (e.g., Rise, Run, Diago-
nal), 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
[Conv] key with the trigonometric function gives you the
arcsine, arccosine and arctangent – all of which are used to find the
angle for the sine, cosine, or tangent value entered.
