Design a sinusoidal function, when this function is called, can print out the amplitude, frequency, phase, linear adjustable sine curve, the specific requirements:
1. The amplitude, frequency, phase, linear, respectively is the function of input parameters;
2. Need to have the main function calls the function, the main function only to obtain input parameters of sinusoidal function,
3. Need to have a coordinate axis

Form put a few Edit to input parameter, a drop-down list box to choose form, put an Image control with its Canvas to draw about, drawing method to check the Help of TCanvas class,
