Exclusive OR. Returns 1 if either value1 or value2—but
not both of them—is non-zero, otherwise returns 0.
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.
Arc cotangent.
ACOT(value)
Arc cosecant.
ACSC(value)
Arc secant.
ASEC(value)
Cotangent: cosx/sinx.
COT(value)
Cosecant: 1/sinx
CSC(value)
Secant: 1/cosx.

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 14-7.
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
for A and B from memory and substitutes them in the
calculation.
To perform symbolic calculations, for example symbolic
differentiations and integrations, you need to use formal
, the calculator retrieves the values
