Homework Sourseidentify the period horizontal shift and phase of ycospi xpi
identify the period, horizontal shift, and phase of y=cos(pi x-pi/4). do not sketch the graph.
identify the period, horizontal shift, and phase of y=cos(pi x-pi/4). do not sketch the graph.
identify the period, horizontal shift, and phase of y=cos(pi x-pi/4). do not sketch the graph.
Solution
period = 2pi/pi = 2
horizontal shift = pi/4
phase = pi x - pi/4
