This applet allows for two trigonometric functions with upper and lower to be introduced using input boxes.[br]The x axis can be toggled between degrees to radians using a button, and limits set using input box.[br]This applet lets the user study the various trigonometric functions and impact on changes of the coefficients a, b & c [br]where the trigonometric function is of the form f(x) = a sin(bx) + c ; a cos(bx) + c or a tan(bx) + c

What is the effect of changing "a"?[br]What is the amplitude of the given function?[br][br]How does "b" affect the number of cycles (repeat of basic patterns) in 360 degrees or 2 pi radians?[br]What is the period (for 1 cycle) of the given function?[br][br]What is the effect of changing "c"?[br]Is there a shift of the axis of the curve of the function ? and in which direction?
