How do I get the gradient at a point on a curved graph?
I have a plot of experimental data and I inserted an exponential trendline
that fits the data very well. I'd like to "differentiate" the curve as I need its gradient at certain points; as in I need Excel to draw the tangent to the trendline at a given point and tell me its equation. Can anyone help me do this? Thank you all so much. |
