Defining functions on Casio 991ES Plus and 115ES Plus

[lrdheat]

On the MathPrint, once a function is defined in table, one can access them from the work space, and use these functions in the work space. For a function defined in f(x), if one is in the work space and wants to integrate f(x) from 0 to 1, for example, from the work space, choose the integration operation, press table and pick #2. This will enter f(x. Complete the entry with ), making it f(x). Enter the range over which to integrate, and it will integrate the function that was defined in table #1 which is stored in table #2 as f(x). Pretty nice!
