+130 A sine function has the following key features:
Period = 4
Amplitude = 3
Midline: y= −1
y-intercept: (0, -1)
The function is not a reflection of its parent function over the x-axis.
Use the sine tool to graph the function. The first point must be on the midline and the second point must be a maximum or minimum value on the graph closest to the first point.
+36914 Sin function
sin (x)
Not reflected
sin(x)
Period = 4
sin ( pi/2 * x)
Amplitude 3
3 sin (pi/2 *x)
Midline y = -1 (shifted down 1)
3 sin (pi/2 * x ) -1
y-interxcept = -1 ...... does not change this sin wave.....
