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
In graph, y = a sin bx +c, what does b refer to?
In graph, y = a sin bx +c, what does c does to the graph?
c will shift the graph up or down depending on the sign. [br]+c will shift the entire graph up by c. [br]-c will shift the entire graph down by c.
In the graph of [math]y=3cos2x-1[/math], state the amplitude and period.
Amplitude: 3 [br]Period: [math]\frac{360}{2}[/math]= 180 degrees
