y = Asin(ωt + φo)

v = ωAcos(ωt + φo)

a = -ω²Asin(ωt + φo)

Where a is acceleration, v is velocity, ω is angular velocity, A is amplitude.

The book uses the following figures:

Figure a) --> http://tinypic.com/view.php?pic=30m8f9j&s=8

Figure b) --> http://tinypic.com/view.php?pic=2hrejde&s=8

Figure c) --> http://tinypic.com/view.php?pic=a0f9te&s=8

In the first case a) what I'm seeing is that the sine in the triangle whose hypotenuse is R and opposite side vector y is (vector y)/(vector R), in this case R is the amplitude.

The rest b) and c) are just complicated, I don't understand them. Anyone out there to help me here?

Thank you!
