Period on a cos graph
WebUsing a graphing calculator or other graphing device, estimate the x- and y- values of the maximum point for the graph (the first such point where x > 0). It may be helpful to express the x-value as a multiple of π. Therefore: y(max)= 1. x(max)= π/4 + 2πn (n is an integer) Now consider other graphs of the form y = A sin x + B cos x for ... WebFeb 13, 2024 · By plotting those points and filling in the sinusoidal axis you can observe a cosine graph. The amplitude is 6 so a = 6. There is no vertical reflection. since the period is 12 you can determine the frequency b : 12 = 2π b → b = π 6 The vertical shift is 12 so d = 12. Thus you have all the pieces to make an algebraic model:

WebWe know y=cos (x) completes a full cycle or period for every change of 2π radians along the x-axis, and as a consequence cos (2π) = cos (0). y=cos (2x) completes a full cycle for every change of π radians along the x-axis, and when x = π, cos (2x) = cos (2 * π) = cos (0). So, for a given change in x, cos (2x) completes more cycles than cos (x).
