Yup!

I was thinking multiplying by \(\dfrac{x}{x}\) would be simpler.

I doubt you know L'hopital? And won't they give you the same thing, Siths?
anonymous
  • anonymous
No I don't no L'hopital ? & umm let me try

Yes, but not if you separate the limits: \[\lim_{x\to0}\frac{\cos x-1}{\sin x}\cdot\frac{x}{x}=\color{blue}{\lim_{x\to0}\frac{\cos x-1}{x}}\cdot\color{red}{\lim_{x\to0}\frac{x}{\sin x}}\]

Sith, I don't think she's that far in calc :3 Let's just stick to the basics for now

  • anonymous
lol i'm in cal 1

These limits are usually presented early on in the course. The blue is equivalent to 0, the red to 1.
anonymous
  • anonymous
oh so the answer would be 0 right? because they are being multiplied together
Luigi0210
  • Luigi0210
Pretty much, right?
anonymous
  • anonymous
Yes. Have you learned these limits yet?
anonymous
  • anonymous
not really :/ my professor briefly went over limits using trig functions so i'm confused :(

Don't worry, you got us :3
