Well, it seems to be a shared experience in my area, since most people do not know the uses of all these numbers. What is sine? "Just a word, who cares." could be a typical answer. "Since those are NOT identities, I can certainly see the possiblity that the people you were speaking to had no...

Sadly, people just accept things such as sin/cos without any further thinking, and then go on. For example, and that is, a very sad one, when you start learning about the circumference and area of a circle, teachers often skip the foundations..."Pi=3.14...it works, just use it." hahaha...

Haha, yes, I meant it in radians sorry, I know that pi=3.14:blushing: . As for my example of arctan, I just used the first equation that I could find containing both, regardless of the real meaning in that equation. It was more of an example, to elaborate. So I could ask again... What would...

I've ask around, and to my surprise, not many people knew what trigonometric identities stood for, and what they really meant. It may seem sutpidly easy to some, but it can also be challenging to others. For example, people (meaning people with an education, at my level, calc 1...)seemed to be...
