As we study the unit circle please know your time and dedication to this topic is very well spent. The Unit Circle is one of the big building blocks of Trigonometry, our focus in Q4.

Hi this is Brooke Ryan from block C pre calc. I struggled with this part of the unit. The unit circle confused me and I don't really understand why we use it. I hope that as we study it more, I will master it. I think that this unit was the trickiest of the trigonometry units.
Hi it's Thomas Moylan from block C. This picture connects the past unit of SOH CAH TOA into our current unit of circles. I'm guessing that we will work with triangles while using radians. In addition, the unit circle has X&Y point values based off a radius of one. This will probably be added to our charts soon and be committed to memory.
Hi, this is Nikki Clover from C Block, and I found the youtube video very informative and it made memorizing the circle much easier.

For me, the unit circle wasn't too hard. It makes a lot of sense the way it is divided up. Even if you forget it, it is easy to figure it out on your own again. I don't really see where else it could be used in our lives, but it definitely helps in math class. I like how everything about the degrees and radians intertwines, and everything comes full circle. Since we've started using radians, I've seen a land surveyor outside, and I knew exactly what he was doing, and how he was doing it, so it was nice to see a real world example that connects to what we are working on in class!
Hi this is leah from block c pre-calc. The video helped me to remember some tricks from finding the equivalent values in degrees and radians. But i am still kind of confused on how to find the points that go with degree and radian values so this might help to go over in class!
Hi this is Mikayla Meyer from Block C Pre Calc. When first introduced to the Unit Circle I was very confused and did not quite understand where all the numbers came from. Then, once we went over it in class the next day with Ms.Gambale and broke the big circle down into three separate circles it made it much easier for me to understand. As we have progressed though chapter 7, i have really begum to understand how truly important the Unit Circle is. I am thankful that we thoroughly learned, and I know that our knowledge of it will only continue to benefit us in the future.

When we first started on this unit, I was a tad bit confused, the whole radians and pi things confused me. Then in about 15 minutes I realized it wasn't as extremely hard or complicated, just new. At least that's what I thought because I clearly did not study well enough for the test =) but I will master this!
Hi this is Sabrina from Block C Pre Calc. I was very confused when we first started learning about the unit circle. I think the thing that helped me the most was going back and forth just converting from degrees to radians like we had to do on the test. It helped me understand and memorize the unit circle better. It definitely makes it better to know you can figure out the circle on your own if you can't memorize it.
This is Hannah from blockC. I agree that I don't really know what it's used for. I also think that it was the hardest of the trigonometry that we did. I haven't memorized it either, but I hope to soon.
Hi this is Tiffany Kirk from Block C Pre Calc. This unit circle was something I didn't understand at first and I didn't understand the radians form of the angles up until I was explained it in class today. I learned that 45 degrees is always in terms of pie/4 and that 30 degrees is in terms of pie/6. Before this explanation in class I would not have understood it. The unit circle is really important when continuing Pre-Calc and it will be very helpful having a good knowledge of it in College next year.
Hi this is Jackie Lusk from Pre-Calc during Block C. I really enjoy the concept of the unit circle. When we were first introduced to it I was very confused... it looked like a whole new language and it seemed like it was going to be hard to learn. However, after Ms.Gambale and the class went into more depth about it and we practiced it a few more times it was like a light bulb went off! It became so easy. I like when things happen that way, when finally something just hits you and it becomes so much easier to understand. I tend to like math and science more than history and english, because of the way the answers are either right or wrong, there's no in-between. Therefore I am looking forward to learning the Quarter 4 material and the unit circle's involvement.
Hi this is Matt Comerford from Block C Pre Calculus. When we were first taught the unit circle I was unsure how this related to what we are doing. But after working for a few weeks now in Chapter 7 I am able to see how it can be used in a wide variety of ways such as special right triangles and radians. I found that it can also help when I am stuck on a test. I am eager to learn more about the unit circle.
This is Lexi from C Block. As many people have said before me, the unit circle was a little tough. At first glance it looks very confusing when it has the radian measurements. Once I went home and drew out the circle for myself and used different colors so I could show myself the similarities between the angles, I really started to get what the unit circle was and how I could apply this new subject to my pre-calc and trig skills. The video listed in this post was also a very gold review of with the circle is and will be helpful if I ever need another review.
I agree with what Hannah is saying. It is always nice to see something that we learn about in school being applied to our everyday lives. Although, as Hannah mentioned, the unit circle might not be one of these things, radians and the type of problems that we have been doing in class definitely are.
Hey this is Aaron from Block C, I must admit that at first i didn't quite understand this part when we learned it in class. I found that personally, simply reducing each fraction so that I could mentally figure out what the measure was proved most helpful. The video seemed to help me but it seems that with a topic like this, repetition is the name of the game.
