Frequently Asked Questions
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 (CONST) and then input the two-digit number that corresponds to the constant you want.
Example 1: To input the scientific constant C0 (speed of light in a vacuum), and display its value
- (CONST)
- (C0)
Example 2: To calculate C0 = 1 √ε0μ0 (MthIO-MathO)
- 1(CONST)(ε0)
(CONST)(μ0)
The following shows the two-digit numbers for each of the scientific constants.
