HP48GX - How to plot tangent line of function? - thomasross - 10-15-2017 07:42 PM
Hello, If I have a function plotted is there a way to quickly plot the tangent line at a point? RE: HP48GX - How to plot tangent line of function? - joeres - 10-15-2017 11:35 PM

You could take the derivative of the function and plot that with the same axes and scaling. |
