Why we avoid the law of sines over the law of cosines with ambiguous triangles

The video tutorial covers the concepts of sine and cosine inverse functions, focusing on their domain restrictions and how these affect angle calculations. It explains the relationships between angles, reflections, and cofunction identities. The tutorial also discusses the implications of these restrictions when dealing with triangles, particularly in the context of the law of sines and cosines, highlighting the challenges in determining obtuse angles.
