Geometry trig

Right angled triangle trigonometry is usually taught before the formal definition and notation of functions. The correct labelling of sides as opp or adj depending on the angle being considered implicity brings in the concept of a function.

Harry_the_cat is correct. I’m being introduced to these concepts.

Pka, with respect I disgree. It seems rachelmaddie is just beginning to learn right-angled triangle trigonometry, where sine, cosine and tangent are defined as ratios. This is usually the way these concepts are introduced. I think her issue is twofold. 1. Not being able to identify sides opp and adj an angle and 2. Simplifying ratios involving surds.
I also don't see how my responses can be detrimental to other students reading this thread.

rachelmaddie has another problem!

S/he has no patience to READ responses CAREFULLY.

I pointed out - long ago (response #21) - that the response-needed included sine, cosine and tangent of the angle M.

S/he continued responding with just numbers - e.g. 4/2 - without any reference to "what does it equal to" or how did s/he got there.

I gave up responding at that point - concluding she needs a face-2-face tutor.

I do agree with pka regarding responding to his/her "repeated" and "careless" answers are "propagating" the "fake news" (false answers) created.

I am not carelessly answering questions. I am answering questions to the best of my ability. I have difficulty with applying these mathematical concepts. I am still learning trigonometric ratios. I have responded with the ratios and also stated that I need help with simplifying radicals.
