ok, so all you have to do is draw out the function and I guess just look at it.

yes, but can you plz exactly say where it is increasing?
ggrree
  • ggrree
notice that it starts at -5, right? it keeps going up from there. it's still moving up once it crosses the x axis.
ggrree
  • ggrree
once it hits pi, it starts to move down instead.
ggrree
  • ggrree
therefore your answer is [0, pi]. hopefully that helped.
