Degree Button

Pressing the degree button, an angle is measured in degrees, minutes and seconds instead of radians. The degree button is important by trigonometric functions. By the functions sin, cos and tan it indicates that the argument is measured in degrees; by the functions arcsin, arccos and arctan it indicates that the result is calculated in degrees.

Equal Button

If you press the equal button the input expression is evaluated. The result is displayed as a decimal number.

Equal Mixed Fraction Button

Equal Degree Button

If you press this button the input expression is evaluated. The result is displayed in degrees/minutes/seconds

Answer Button

The last calculated result (the right side of the equal sign "=") is inserted in the current expression. This button is ideal to be used in iterations.
