btw the top equation where it says neq..it is actually supposed to say not equal to x

anonymous · Answer

If x is outside of the usual domain of arcsin, you will not get x as your answer for part (i). Part (ii) is just asking the domain of arcsin in a very sneaky way.
To get neq to work, try placing a backslash to the left of it and a space to its right: a\neq b becomes $$a\neq b$$when placed in the brackets which trigger LaTeX on this site.

so would the first one be something like this by puting x outside? |dw:1368605515355:dw|
