WebFind Amplitude, Midline, and Period/Frequency of if you start a cosine function (presumably starting with y = 0) it should read 1, wheareas if you are plotting a sine … Web20 jan. 2024 · 2 Answers By Expert Tutors. The amplitude of the parent function, y = cos (x) is 1, so A must equal 3 to create an amplitude of 3. The midline of the parent function is 0, so D must be 4 in order to translate the graph up 4 units, moving the midline to 4. B is the tricky one. Keep in mind that the Period = 2π/B.

WebGraph of the basic cosine function. To graph the cosine function, we plot the angle along the horizontal x-axis, and for each angle, we place the cosine of that angle on the vertical y-axis. The result of this is a curve ranging from +1 to -1. The curves that follow this figure are called sinusoids. The cosine function is a periodic function.
