Hi Nikita,
Try this link to a post I made. I could't grasp Radian measure and the unit circle. The response from HallsofIvy helped it make more sense. Hope this doesn't find you after the exam! :-)

That makes a lot more sense to me than the way is was explained, but it leads to my next trouble spot. How is a radian measured in degrees? This was where I was told to think of it like a "Clock" and that confused me and was unable to perform the calculations.

I need some guidance into understanding Radian Measure and the Unit Circle. This was the topic where I tanked and had to drop the course. I'm going to pick it up again next fall and want to start preparing now.
Any help is appreciated.
