Learn where the formula of oblique triangles come from

The video tutorial explores the relationship between sine and triangles, focusing on labeling conventions for angles and sides. It explains how to calculate the height and area of triangles using trigonometric functions like sine and cosine. The tutorial emphasizes the flexibility in choosing angles for formulas and provides insight into the origins of these formulas, helping students understand their derivation rather than just memorizing them.
