Pythagorean Theorem/Right Triangle Keys - Calculated Industries Sheet Metal/HVAC Pro Calc User Manual

Your calculator has standard trigonometric keys, in addition to Right
Triangle keys (e.g., R, r, d and p), 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 gives you the
Arcsine, Arccosine and Arctangent – all of which are used to find the
Angle for the Sine, Cosine, or Tangent value entered.
