Sine Cosine Tangent

This explains the behavior of the basic sine, cosine and tangent function. You can modify the amplitude and the frequency of the function. In addition you can enter an x value or a periodical step for the solution you require. The app shows every important calculation, provides an info image and displays the graph.
Decimals, fractions, negative values and π are supported. The solution is shown step by step. All calculations are stored in the history. The final solution can be shared.
