Have you graphed each of these functions?
What do you get?
the question is simplY:
solve for 0<x<10
ln(2x+1)<3 cos x
{it is only woth 4 marks, part one, which was worth 2 marks,was what 2 transformations take
ln(x) to ln(2x+1) so i cant see there is to much work here but i cant get it.}
I can see i need to find the points of intersection, but i must be missing something here.
The mark scheme is no help,it just states the answer.
this is what i guessed, but as i say its only 4 marks,compared to the 2 marks for the 2 transformations in part (1).
it gives no starting values and i need 4 numbers (0 being the easy on to find)
on another paper have same sort of question when need to solve e^(-x)-x+1=0, once again mark scheme gives no suggestion as to how the answer is to be found.
