To use a Home
variable in CAS
Computer algebra system (CAS)
The highlighted item is copied to the cursor point in CAS.
You can access Home variables from within the CAS. Home
variables are assigned uppercase letters; CAS variables are
assigned lowercase letters. Thus SIN(x) and SIN(X) will yield
different results.
To use a Home variable in the CAS, simply include its name
in a calculation. For example, suppose in Home view you
have assigned variable Q to 100. Suppose too that you have
assigned variable q to 1000 in the CAS. If you are in the CAS
and enter 5*q, the result is 5000. If had entered 5*Q
instead, the result would be 500.
In a similar way, CAS variables can be used in calculations
in Home view. Thus you can enter 5*q in Home view and get
500, even though q is a CAS variable.
