This applet can be used to see the connection between the graphs of [math]y=e^x[/math] and [math]y = \ln(x)[/math]. It can also be used to gain an appreciation of the derivative (gradient) of the natural log function [math]\ln(x)[/math]. This can be used to introduce the exponential function and natural logarithm in the A-level OCR Core 3 module.
