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. [ Contents ] - modes for a logarithmic and an exponential function - all inputs have default values, but can be changed - results are calculated and shown in detail - 5 parameters to change the function - 1 parameter to calculate a certain value - infographic to show the effect of the parameters - history function to save the input - detailed solution - negative values, decimal numbers and fractions are supported - no ads! [ Usage ] - there are fields for entering values using a special keyboard - press the check mark button at the bottom right to start the calculation - if values are missing, the relevant field is highlighted in yellow - if the values are wrong, the affected field will be highlighted in red - the entries in the history can be deleted or sorted - if you select an entry in the history, it will be automatically loaded for the calculation - the whole history can be deleted by pressing a button - solutions can be shared - touching the question mark button displays information about the topic
