The video tutorial covers the basics of right triangles and trigonometric functions, including sine, cosine, and tangent. It explains how these functions relate to the sides of a triangle and their behavior in different quadrants. The tutorial also provides examples of calculating trigonometric functions for specific points, demonstrating the process of plotting points, forming triangles, and using the Pythagorean theorem to find the hypotenuse. The mnemonic 'All Students Take Calculus' is introduced to help remember the signs of trigonometric functions in each quadrant.
