The Fourier Transform expresses a function of time in terms of the amplitude of each of its frequencies. In addition the Fourier Transform a method of decomposing any wave into a series of sine waves.

The Fourier Sine Transform IPad apps creates a Fourier Transform Sine Wave and a Sine/Cosine Interpolation Curve.

The app has two data input fields that exist for the entry of two data parameters for the Fourier Sine Transform: the Interval (a), the Interval (b). A slider is utilized for the input of the Number of Steps

The Fourier Sine Interplant Graph is a touch interactive graph for computed (x/Sine/Cosine Interpolant Wave intersect paired values. The graph has a touch feature whereby upon the touch a slidable vertical line appears. Upon movement of the line the paired values appear relative to the line position on the graph curve.

The horizontal x-axis displays computed (x) values. The vertical y-axis plots a range of Sine/Cosine Interpolant Wave intersect values
