Power and Logarithmic function app for iPhone and iPad

Exponential function and logarithm are inverse to each other. This app shows how to create the inverses. It also provides a short curve analyse with significant properties and a graph. Everything is shown step by step. All calculation processes are easy to follow.
It is also perfect to fiddle with the logarithmic and the exponential function by changing several parameters. Changing the parameters affect the result like shifting or stretching the graph. An infographic shows the effect of each parameter.

Decimals, fractions and negative values are supported. The solution is shown step by step. All calculations are stored in the history. The final solution can be shared.
