Dec 2, 2024 · I'm learning trigonometry, and I'm confused about the representations of trig functions on the unit circle: I understand why sin and cos are placed like that (sin (x) = O/H = O/1 = O, etc.) but …

Dec 4, 2018 · I first learned that arcsin and inverse sine are two ways of saying the same thing. But then I was thinking about the inverse sine function being a function, so it must be limited in it's range fr...

May 31, 2016 · The restrictions for the regular trig functions should be the the same but the range and domain's values are switched if I'm not mistaken. These were the main problems that made me …

Sep 1, 2022 · In the old days we had trig tables (values of trig functions for angles from 0 to 90 - whole degrees). So to find inverse, you would look up the value of function in the table and find …

Mar 18, 2020 · I see here a list of inverse trigonometric functions written in terms of logarithms. The ones I'm most interested in for the purposes of this question are $\arcsin {z}=-i\ln\left (iz+\sqrt {1 …

Mar 6, 2021 · I remember the derivatives of trig functions by naming 3x basic right triangles in a specific way and using ONE simple multiplication. Just wondering if there are similar approaches to …

Nov 29, 2017 · I read from my textbook that since trig functions (sin and cos) don't pass the horizontal line test, so to be able to consider its inverse function, we have to restrict the domain of the original …

The limit of an inverse trig function. Ask Question Asked 12 years, 1 month ago Modified 12 years, 1 month ago

The answers seems so close and I was wondering (a) am I right? But more importantly, (b) is there some relationship between $-\arccos (-x)$ and $\arccos x$. More generally, is there a relationship …

However, I have noticed that every domain restriction for inverse trig functions contains the whole first quadrant in its entirety (with the exception of x values where there are vertical asymptopes).
