comment solution to inverse trig function, decimals
but what about the other answer? do I just exclude it because it is a decimal? it doesn't seem like the right way

sort-of, but, the domain of x is. for all x in real numbers, not between [-pi, pi]. unless that's the only way to express the answer? but I could be just doing the problem wrong, idk

yes but, if the answer is correct, how can I express that decimal in terms of pi without decimals?

comment How can I solve: ${\left [{x+1}\over2\right]}={x-1\over 3}$?
is this a algebra question?

for #2(edited) is this right? any comment on #3 not being a equation? therefore shouldn't be attempted?

#4. i still come out with the same end if i use identities, and get sin(x) on one side. do i just divide end angles by 2 using sin(2x)?

#1) i came out with cot(x) = -1, but i can also get tan(x) = -1. are both the same answer? #5) why cot(x) = 0 ?
