Constant calculations
• In constant calculations, the addend becomes a constant. Subtraction
and division behave the same way. For multiplication, the multiplicand
becomes a constant.
• In constant calculations, constants will be displayed as ∆.
Functions
• The range of the results of inverse trigonometric functions
