How To Memorize The Unit Circle Based On Patterns

i do for the last quadrant. Now that you all the pi! You can open 5 7/11's!

i hate everything about this

this helped a lot, thanks! best video i've watched so far

There is no reason to memorize the unit circle. The easy way to produce the unit circle is to divide a circle into 24 equal 15 degree graduations. Number these points from zero Pi to 2 Pi 0,1,2,3... then take those numbers and multiply them by Pi/12. You will have 8 extra locations on the your unit circle that you can use or throw away. The same method can be used to give you any number of equal graduations that is an even number. Just change the denominator to half that number.

3 years later. I finally get it.

For the 4th quad. You can do den.X2 -1 = Numerator.
Ex: 6x2=12... 12-1= 11pi as the num.
