Illustrating the Derivative of Natural Log

Illustrate the natural logarithm function y=ln(x) and its derivative y=1/x by drawing the curve of the function, then at a specific point on the curve, sketch the tangent line and display its slope to help understand the concept of derivatives. First, plot the natural logarithm function, then select a point on the curve, draw the tangent line through this point, and label the slope of the tangent line to show the instantaneous rate of change of the function at that point.
