hey everyone, i am new here and i need help as i have final today.
I have no problem with dealing with limits, but i am having troubles with this one.
lim sin(x^2) / [ ( e^x ) - x - 1 ]
first, I know that this problem should be solved using l'hopital's rule.
as i did it using it, i got to lim [ - cos(x^2) . 2x . 2x . 2x ] / e^x
so my answer would be zero.
is this right? because my teacher said in class that the answer for this should be 2 and i wonder how she got 2.
please anyone would help?
