How do I find limx→0xcot(6x) without using L'hopitals rule?
I'm a freshman in college in the 3rd week of a calculus 1 class. I know the limx→0xcot(6x)=16 by looking at the graph, but I'm not sure how to get here without using L'hopital's rule.
Here is how I solved it (and got the wrong answer). Hopefully someone could tell me where I went wrong.
limx→0xcot(6x)=(limx→0x)(limx→0cot(6x))=(0)((limx→0cos(6x)sin(6x))=(0)(10). Therefore the limit does not exist.
I am also unsure of how to solve limx→0sin(5x)7x2 without using L'hopital's rule.
