Amplitude, Period and Phase Shift of the Sine FunctionThis applet illustrates the Amplitude (a), Period (2π/b) and Phase Shift (c) of the sine function f(x) = a sin(bx + c). Move the sliders for a, b and c to illustrate ths effect of different values of these numbers on the graph of f (in black). Fro the sake of comparison, the simple sine curve y = sin x is illustrated in red. reb, Created with GeoGebra |
