Why special right triangles help use evaluate trig functions

The video tutorial emphasizes focusing on understanding rather than note-taking. It covers the 45-45-90 triangle, explaining the relationship between the legs and hypotenuse. The tutorial also discusses converting between hypotenuse and leg, and the significance of trigonometric functions like sine and cosine. The preferred triangle for trigonometric functions is highlighted, emphasizing its simplicity and ease of use.
