OrCad Spice - plotting tangent line of curve

  1. Feb 9, 2008 #1
    Hi, I'm having trouble plotting the tangent line on a curve (or the derivative evaluated at a point) in spice. I know how to plot the derivative of the entire curve using the d() function, but I don't know how to evaluate it at a point. Any help is much appreciated!

    I don't use OrCad so I probably can't offer much help. But if you can plot the derivative of the entire curve. Why not just put a marker at the point you want. That will tell you the numerical derivative.
