Graph one complete cycle of
y + cos x cos pi over6 + sin x sin pi/6 by first rewriting the right side in the form cos(A-B)

  • trig -

    You probably meant to write
    y = cos x cos pi over6 + sin x sin pi/6 which is
    y = cos(x - pi/6)

    first sketch very faintly, perhaps as a dotted line, the function y = cosx from 0 to 2pi
    then move this graph pi/6 units to the right.
