Graphing Equations: y=cosx/2, y=-2sin2pix/3, y=1+1/2cos4pi/t

[asimon2005]

I need help on to do these problems.

Here they are: y=cos x/2, y=-2 sin 2?x/3, y=1+ 1/2 cos4?t, y=5sin(?-2x) +10, y= -1 + sin 2 (x-?/3), and y=3-2cos 1/2(x+?/4).

I have typed into google for Graphing sine and cosine equations but I couldn't find examples showing one's on advance problems.

You did not look very hard. In order to look hard, you must think.

Did you see anything at all that looked like A sin (Bx + C) + D, where the numbers A, B, C, and D are explained?

If not, then try the following keywords at Google: graphing sinusoidal functions.
