Thanks for the quick reply. So are you saying I should make the function sint/lnt instead of lnt/csct? Wouldn't that still come out with lnt undefined when I plug in 0?

I recently learned about L'Hopital's Rule in calculus and as I was doing some practice problems I came across two that confused me a lot. I was hoping that someone could help me with them here. The problem is lim(t→0)⁡〖(sint)(lnt)〗. I tried to make (sint)(lnt) a quotient by setting the...

Thanks for clarifying.

A limit doesn't exist if the function is not continuous at that point. The way to find out if a limit of a certain function exists or not is to approach the limit from the left and the right side. For example: Take the limit of the function f(x) as x approaches 0. If you approach 0 from...

If that sen(x) is indeed a sec(x) then just use the product rule between x and cos(sec(x)). The -1 becomes 0. When you get the new function derive it again and you'll have f''(x). You might be asking for the answer in which case I won't be giving you because you'll never learn it yourself...

Don't take my word for it but I think that has something to do with probability. At the top where it has this equation that looks similar to H(P/Q) except the slash is straight, I don't know what H stands for but (P/Q) should mean P given Q. Hope that helps. Someone please correct me if I'm...

I created an account on the forum just for this. I thought the answer was 2 when I first saw the equation but now that I've read some of the posts, I'm not so sure anymore. I played around with the equation and set 2 to x like the OP said. From what I can see I think it really comes down...
