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.
S Sine Function — Calculates the sine of an entered
degree or non-dimensioned* 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 non-dimensioned* value.
З з Arccosine (cos -1 ) — Calculates the angle for the
entered or calculated cosine value.
t Tangent Function — Calculates the tangent of a
degree or non-dimensioned* value.
Ç t Arctangent (tan -1 ) — Calculates the angle for the
entered or calculated tangent value.
*Note: Cannot use on dimensioned values.
