Thank you very much again for the help!

Yeah because I wrote it in text...thanks for the help Mark! Also could you point me in the direction of how to represent maths symbols on this forum?

Ohhh yeah I forgot about that, also I'm new here so I'm not familiar with the way people express maths symbols and stuff using code so I'm just going to write it an easier way. How about: (infinity,-1/9) U [1,infinity)?

So... -1/9<x & x<=1?

So would I be right If I concluded that the interval is?: (-9,-1] U (0,1] Since 0 can't be included as we are working with 1/x?

I need help determining the interval notation of the inequality below: -9<1/x<=1

I kinda forgot that I posted this, anyone still willing to help me solve this just for the sake of solving it? Any help is much appreciated!

I found the first derivative to obtain the velocity, but I'm stuck here. I also don't know what to do with the value that is given for theta.

I need help solving all three parts to this question, never seen a question regarding applications of differentiation that is this hard before! All help is much appreciated.
