I'll explain it later. Please bear with me.yes that's the answer, how'd you do that?
random question  how do you type in maths notation? Is there a website or software to switch from maths and natural input?For last one:
QED
It's Latex. Personally I don't know how to use it yet but there is an option on the toolbar in the text box, denoted by "f(x)".random question  how do you type in maths notation? Is there a website or software to switch from maths and natural input?
Recall that the domain of arctan x is all real x. However, for this question you have a restriction, that is the domain of sqrt(x^2  1).How would I find the domain for this?

Actually that guide is a bit outdated.
A Short Guide to LaTeX
Hi everyone, With the use of LaTeX becoming more widespread, I've decided to write a short guide to LaTeX. If you have any problems, post in this thread or message me somehow. jetblack2007. The graphical editor supplied to us is excellent, though I think at least a small amount of knowledge of...boredofstudies.org
So essentially is the domain of the composite function inside brackets transferred into the whole function?Recall that the domain of arctan x is all real x. However, for this question you have a restriction, that is the domain of sqrt(x^2  1).
For the function y = sqrt(x^2  1), the domain is that x >= 1, or x <= 1. Since the domain of arctan x is all real x, the domain of sqrt(x^2  1) is the domain of arctan(sqrt(x^2  1)), that is x >= 1, or x <= 1.
really got the du qns  does the homework hinting stuff or whatever suck that muchHow would I find the domain for this?
Yeah, but that’s only because the parent function (arctan x) has a domain of all real x. If it was a function like arccos x with a domain between 1 and 1 inclusive, I think there would be those restrictions which you’d have to consider.So essentially is the domain of the composite function inside brackets transferred into the whole function?

If I'm being honest, no one really uses it and the homework help zooms are packed every day with at least 6 qns each from each student which correlates to hours upon hours of wait times. So usually what happens is I resort to BOSreally got the du qns  does the homework hinting stuff or whatever suck that much
I'm late but how did u find the domain and range for the second question? And the range for the firstThe other two; are these answers correct?:
let u=e^x, therefore y=arccosu, find the common restriction of 'u' and find D: and R: using both graphsI'm late but how did u find the domain and range for the second question? And the range for the first
