Scientific Constants

Your calculator comes with 40 built-in scientific constants that can be used in

any mode besides BASE-N. Each scientific constant is displayed as a unique

symbol (such as π), which can be used inside of calculations.

To input a scientific constant into a calculation, press 17(CONST) and

then input the two-digit number that corresponds to the constant you want.

To input the scientific constant C

(speed of light in a vacuum), and

display its value

A17(CONST)

28(C

To calculate C
