Most of the problems i understood, but this one was difficult for me:
Sin(arccos(x/3)+arcsin(x))
My answer was (x^2+(x^4-10x^2+9)^1/2)/3
in words, my answer is X squared times the square root of x to the fourth minus 10 x squared plus 9, all of that being divided by 3.
My answer just seems wrong to me? Please help me figure out how to do this problem, and what the correct solution should be. thank you!
