Can someone please explain to me how to do vertical and horizontal shifts in sine and cosine graphs....
for example:
y= 1/2 cos 3(x+ pi/6)
y= -2 + 2cos 1/2x
I know how to find the amplitude, period, frequency and how much am i suppoused to do the shift by but i jst dont know how to graph it...
if someone can please help me i would really appreciate it....
