Trig Grapher
The Trigonometric Grapher is a Win32 program that graphs an adjustable equation onto its window. Sine, cosine, tangent, cotangent, secant, and cosecant function graphs are possible, and they can also be printed with a high resolution. The colors are fully adjustable.
The graphed function is y = A * xyz(B * x + C) + D, where xyz is sin, cos, tan, cot, sec, or csc, depending on what is selected.
Pi can be added to a text field by either typing a "p" in the field or clicking on the "Pi" button and then clicking in a text field with the upwards-pointing mouse cursor.
When the Trigonometric Grapher is printing, the user can graph other functions as the printing happens in a background thread. This was my first multi-threaded program, though its simple architecture sidestepped concurrency issues by not using shared memory between the threads.
I wrote this program while I was taking a trigonometry class in high school.
