OT: Can anyone explain to me how I solve this math exercise?

I am not sure how to start really.
I know [(sin(x))/x] = 1 right?
So do I just put them on the same fraction so I can divide the sin(x) with the x to remove the sin(x)? :D

I am struggling with this.

    I know that I used to know how to do this. Ask me 3 years ago and I'll be able to help.

    Haha, same for me. Countless of problems just like this to solve. Love it :joy:

    Don't remember if L'hospitals rule applies with this or if it only applies when it's devided by something :P

    Is the (x^2+2)/x the power of 1+sinx?

    Actually yes. So my method won't work. Makes it even more unclear what I have to do.

    Use the internet. It says the answer is e^2 :#

    Well yeah but I have to know how they get to the answer. :D

    Or do you have a calculator that gives you the steps?

    By doing quick maths. Having the answer is always better than struggling with the way to get there :trollface:

    I wish my prof thought the same way.

    If it helps you can split up the limit into two different limits:limit of (1+sinx)^x multiplied by limit of (1+sinx)^(2/x). Solve for the first one, and you'll get 1^0 = 1, so we know that the limit of (1+sinx)^(2/x) as x -> 0 is the same as the original question.

    And these are the steps I got online by using lim x->0 (1+sinx)^(2/x):

    It seems easy once you know how to do it, haha.

    Im in that same boat, calculus is a serious struggle. Thank goodness my teacher grades based on the ap scale. I.e. If you get 67% on a test you can correct that up to an a bc that would be a 5 on the ap scale, and if you get a 5 you get an a. So my last test I got a 57% but still end up with a 91% on the section. The system is very nice.

    Holy **** I swear I got a problem almost exactly like that on my calc 2 final exam last semester, but instead of sin(x) it was log(x). I'm so glad I'm done calc but now I'm in discrete mathematics which is all theories and proofs, which just so happens to be the only thing in math I really suck at

    If you thought calc 2 was hard, stay far away from calc 3. I thought integrals were pretty straight forward until they started using equations as the bounds...
