I was trying to figure out a way to remember the Unit Circle after scratching my head for a while i finally figured out some patterns...
I looked multiple images on the Internet and couldn't find any better representation of unit Circle...
So i made one myself listing all the patterns and ways to remember Unit Circle.
Patterns :
3 -> 4 -> 6 color coded in light pink
On top left (2nd quadrant) you can find the numerator of the radians by subtracting 1 from the denominator N - 1
And for the bottom left (3rd quadrant) N + 1
Btw radians are just circumference of a Unit Circle upto a certain point...
360 deg = (2πr where r = 1)
You have to remember 4th quadrant!
