For the longest time, graphing calculators have not changed in terms of design and function, as they all centered on solving algebra and other math problems that could take more time to solve on paper ...

Plotting a graph takes time. Often mathematicians just want to know the key features. These are: shape, location and some key points (such as where the graph crosses the axes or turning points). So ...
