In order to get a good score in math for the SAT we have to learn, practice, practice, and practice. The first day in math Jeff (our math teacher) asked us to note down all the section the students want to improve so he can fill in all the gaps for us in the next two months. Based on the majority most of us wants to work on the unit circles.
The equation itself it looked so scary. I think in my head “do I have to memorize all the equations? How can find all the angles in our head? Do we need to use a calculator?” All the questions were clear after I took a few lessons in one hour. It’s easy than it looked. I can’t say the unit circle is easy, but in order to feel confident, and to solve it quickly, I need to practice and most importantly I need to find my own strategies.
After I learned new strategies in class and practiced in Khan Academy, I’m able to draw my own unit circle of all the trigs values of special angles (90°, 45°, 30°, and 60°).
Check it out! My first unit circle.
