HEET METAL/HVAC PRO CALC
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.
S Sine Function — Calculates the Sine of a Degree
or undimensioned* value.
Ç S Arcsine (sin
-1
) — Calculates the angle for the
entered or calculated Sine value.
ç Cosine Function — Calculates the Cosine of a
Degree or undimensioned* value.
Ç ç Arccosine (cos
-1
) — Calculates the angle for the
entered or calculated Cosine value.
t Tangent Function — Calculates the Tangent of a
Degree or undimensioned* value.
Ç t Arctangent (tan
-1
) — Calculates the angle for the
entered or calculated Tangent value.
*Note: Cannot use on dimensioned values.
