XOR | Exclusive OR. Returns 1 if either value1 or |
| not both of |
| value1 XOR value2 |
| The trigonometry functions can also take complex |
| numbers as arguments. For SIN, COS, TAN, ASIN, |
| ACOS, and ATAN, see the Keyboard category. |
ACOT | Arc cotangent. |
| ACOT(value) |
ACSC | Arc cosecant. |
| ACSC(value) |
ASEC | Arc secant. |
| ASEC(value) |
COT | Cotangent: cosx/sinx. |
| COT(value) |
CSC | Cosecant: 1/sinx |
| CSC(value) |
SEC | Secant: 1/cosx. |
| SEC(value) |
Although CAS provides the richest environment for performing symbolic calculations, you can perform some symbolic calculations in HOME and with the Function aplet. CAS functions that you can perform in HOME (such as DERVX and INTVX) are discussed in “Using CAS functions in HOME” on page
In HOME | When you perform calculations that contain normal | |
| variables, the calculator substitutes values for any | |
| variables. For example, if you enter A+B on the command | |
| line and press | , the calculator retrieves the values |
| for A and B from memory and substitutes them in the | |
| calculation. |
|
Using formal | To perform symbolic calculations, for example symbolic | |
variables | differentiations and integrations, you need to use formal |
