Today we learned about the unit circle. (shown above)
We continued to explore Trig and the uses of Sin and Cos.
X coordinate- Cos
Y coordinate- Sin
the positive degrees on the unit circle goes counter clockwise starting in the right
(x on the picture above)
they go 0-90-180-270-360
opposite if you are moving in the negative direction
check out the notes for a better explination..
Remember the homework was changed to just the top problems on the assignment sheet ( 1,4-7,13,15-17, 21) because we did not finish the lesson and there is a quiz tomorrow :)
