Calculated Industries 44080 Construction Master Pro Desktop v3.0 User Manual page 25

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.
