Since This means we can make as close to zero as we wish by making sufficiently close to . Thus we can make as large as we wish by making sufficiently close to .
We can be a little more precise with a definition if you wish.
Can someone explain why the limit of the function 1/sin²x is ∞ as x approaches 0(from both left and right).
I'm just starting to learn this, so as simple an explanation as you can manage would be appreciated.
What does the graph of 1/sin² x look like?
