The video tutorial covers trigonometric functions, focusing on solving right triangles when given one angle and one side. It explains the sine, cosine, and tangent ratios, and demonstrates how to use these ratios to solve for unknown sides of a triangle. The tutorial provides step-by-step calculations for finding side A using the tangent ratio and the hypotenuse using the cosine ratio.
