SciPlus-2200 Scientific Calculator – User Guide

Trigonometry

Trigonometry functions are very straightforward with the SciPlus-2200. Note that the values used in
trigonometry functions, and the result, are expressed in Degrees, Radians, or Gradians, as indicated by
‘D’ ‘R’ or ‘G’ in the status line.

KEY

NAME

DESCRIPTION

Sine

Calculates the sine of an expression.
e.g. (assume degrees):

SIN( 30 )

followed by

↵

yields 0.5.

Arcsine

Calculates the inverse sine (arcsine) of an expression.
e.g. (assume degrees):

ASIN( 0.5 )

followed by

↵

yields 30.

Set Angle Mode

This simply toggles through Degrees, Radians, Gradians. The current
setting is indicated in the status line. After setting this parameter,
subsequent input values and the results of expressions are expressed
accordingly.

Convert Angle

Converts the current value displayed in the

second line

, and changes

the status line parameter.

The Cosine and Tangent functions, and their inversions, work the same way.
