    |dw:1383613163684:dw|The y component gives us the value for sine. So what is the length of that line in the y direction? It's the radius of the circle yes?

    Do you understand how to find sine and cosine of \(\large 90^o\)? If you can do those two, you can build all the other trig relations off of those.

    If you're just using a chart or some way to memorize sine and cosine, then that's fine also :o
