The Context Panel provides access to the options All Solutions, Next Step, and Limit Rules, as per the figure to the right.

While the Context Panel lists both a "difference" and a "sum" rule, Maple treats a difference as if it were a sum, thereby making no essential distinction between the two rules. Thus, where Table 1.3.1 distinguishes between a Sum and a Difference rule, Maple considers both to be the single Sum rule.

In addition, the Student Calculus1 package contains a ShowSolution command that can be applied to the inert form of the limit operator. The limit operator can be converted to the inert form through the Context Panel by selecting the options 2-D Math≻Convert To≻Inert Form.

Notice how Maple first deals with the factor of 2, then carefully moves the limit inside the square root and applies the sum rule to . All of these precise details are incorporated into the "reasoning" at the end of the Mathematical Solution in the previous subsection.
This solution, or a shorter one, can be obtained with the
tutor. Selecting, for example, the Constant Multiple rule in the menu "Understood Rules" will suppress the step in which that rule is explicitly invoked.
