Modifying the Live Symbolic Operator

If you need to symbolically evaluate an expression in a particular way, use a keyword to modify the live symbolic operator. To do so:

  1. Type the expression.

    (x + y) cubed

  2. Press [Ctrl][Shift][.] to insert a placeholder and the symbolic equal sign.

    (x + y) cubed placeholder symbolic equals

  3. Type a keyword in the placeholder or choose a keyword from the Symbolic toolbar. If the keyword takes a modifier, type a comma followed by the modifier. If there is more than one, type them separated by commas.

    (x + y) cubed expand symbolic equals

  4. Press [Enter].

The symbolic processor returns a result based on the keyword you typed. You can symbolically evaluate this result further by using several keywords.
