| This paired set of aplets, based around the Function and Solve aplets, allow the user to quickly and easily find the features of functions such as intercepts and extrema using derivatives, automatically finding the derivative functions as part of the process. Obviously this is something which can already be done with the Function aplet but these two aplets automate the process by switching automatically between the abilities of the Function and Solve aplets. As an examination tool it is definitely worth having. |
