  12. Amplitude • The amplitude of the graphs of y=asinx and y=acosx is |a|. • What if “a” is a negative number? • Link

  13. Period • The period of the graphs of y=sin(bx) and y=cos(bx) is • Link

  14. Phase Shift • The phase shift of the graphs of y=sin(bx-c) and y=cos(bx-c) is c/b. • Link

  15. Vertical Shift • The vertical shift of the graphs of y=sinx+d and y=cosx+d is d. • Link

  16. “Graph” the following: Amplitude: Period: Phase Shift: Vertical Shift:
