Cosine limit

  1. Oct 19, 2009 #1
    I'm trying to remember a limit I was supposed to have memorized for calc. Is this right?


    limx-->0 [Cosx - 1]/x = 0


    I know it was something like that, but I'm not sure

    Thanks

    That's right. You can find the limit by using some algebra and limx→0 sinx/x = 1

    I call that limit cos'(0)=-sin(0)=0
