Hello, I have been doing some trigonometry lately, just trying to get the trig I need for calculus, and the book I am reading goes into inverse trig functions. The book dives into trig equations without giving a very good description of how to find the trig functions. I understand how to do stuff like cos^-1(2) in the calculator, and also how to flip the other reciprocal function, but this is where my understanding fizzles out: once you get the answer in the calculator, what operations do you perform on it? Because from what I understand, the answer you get in the calculator isn't the final answer. The answer to my question is probably very simple, but I would sincerely appreciate it if anyone could help me with this, because I'm itching to get through the trig and into calculus. Also, how much trig is required to sufficiently understand calculus?
