The video tutorial explains the unit circle and its relationship with cosine and sine coordinates. It introduces the acronym ASAP to help memorize the unit circle, with each letter representing a different quadrant: 'All' for the first quadrant, 'Subtract' for the second, 'Ad' for the third, and 'Prime' for the fourth. Each quadrant has a unique method for determining the numerators of radians, aiding in memorization and understanding of the unit circle.
