Question

Find by numerical experimentation all the positive integers k such that the limit as x approaches zero of sin*[(sin^2)x]/x^k exists. There is a single value of k for which this limit isn't zero. what is this k, and what is the resulting limit?

Answer 1

numerical experimentation?

Answer 2

investigation? the question actually says experimentation

Answer 3

ok

Answer 4

I really need help with this one

Answer 5

k=2,the limit is 1

Answer 6

can you help with the why?

Answer 7

sorry,i missed many steps,but did u understand what i did?
