How to find Slope at plotfield() point - MullenJohn - 09-07-2018 02:44 PM How do you show the slope at a point of the plotfield() graph? Using the geometry APP the plotfield() graph show the slanted line for a point but I cannot find how to determine the slope of the slanted line at the point. Is there a way for the HP Prime to determine the slope at the point? Thanks - Cheers!
