Why is trigonometry so hard?

Why is trigonometry so onerous?

Trigonometry is onerous as a result of it intentionally makes troublesome what is at coronary heart straightforward. We all know trig is about proper triangles, and proper triangles are in regards to the Pythagorean Theorem. Concerning the easiest math we will write is When this is the Pythagorean Theorem, we’re referring to a proper isosceles triangle.

Does trigonometry work on all triangles?

No, they work for all triangles. The phrase, trigonometry, itself stems from Greek, and it means measuring triangles. There are guidelines that solely pertain to proper triangles, however they’re actually simply the particular case the place one angle is 90 degr. A restricted, if essential, use.
