## Angle measure

If you choose Degrees, all arguments of the trigonometric functions will be considered to be in degrees and the inverse trigonometric functions will give results expressed in degrees.

Similarly if you choose Radians, all arguments of the trigonometric functions will be considered as being in radians and the inverse trigonometric functions will give results expressed in radians.

The unit of angles is displayed in the top banner of the screen as deg or rad.

## Result format

If you choose Auto, the numerical values will be displayed according to calculator presets so that they are as appropriate as possible for each application.

If you choose Scientific, the numerical values will be displayed in scientific form. A sci indicator then appears in the top banner of the screen to indicate that your results are displayed in scientific notation.

You can choose the number of digits to display for the results by directly modifying the value in the section Significant figures. The maximum number of digits that can be displayed is 14.

## Complex format

If you choose $a+ib$, complex results will be displayed in rectangular form.

If you choose $re^{i \theta}$, complex results will be displayed in polar form. In this case, the argument in the exponential will always be given in radians, even if the angle unit is set to Degrees.

## Brightness
