To use a function, type the letters that represent the function, and then surround the expression in that function with parentheses. For example, to represent the square root of
You can use the following functions:
- Common functions:
- Trigonometric functions and their inverses, as well as hyperbolic trigonometric functions and their inverses:
Function Inverse Hyperbolic Function Inverse sin arcsin sinh arcsinh cos arccos cosh arccosh tan arctan tanh arctanh sec arcsec sech arcsech csc arccsc csch arccsch cot arccot coth arccoth
Factorials: Enter factorials as
factorial(3). You must use integers. For example, you cannot enter
- A “parallel resistors” operator (
||). For example,
1 || 2represents the resistance of a pair of parallel resistors (of resistance 1 and 2 ohms), evaluating to 2/3 (ohms).
