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

— Calculates the 

Sine

of an entered

degree or non-dimensioned* value.

Ç S

— Calculates the angle for the

entered or calculated Sine value.

ç

— Calculates the 

Cosine

of a

degree or non-dimensioned* value.

Ç ç

— Calculates the angle for the

entered or calculated Cosine value.

t

— Calculates the 

Tangent

of a

degree or non-dimensioned* value.

Ç t

— Calculates the angle for the

entered or calculated Tangent value.

*Cannot use on dimensioned values.
