The video tutorial introduces two methods to remember exact trigonometric values for specific angles: 0, 30, 45, 60, and 90 degrees. The first method involves using a table to calculate sine, cosine, and tangent values by dividing by two and applying square roots. The second method, introduced at the end, involves a hand trick for those who find the table method challenging. The tutorial emphasizes understanding the unit circle and the repetitive nature of trigonometric functions, while focusing on practical calculation techniques.
