using L'Hospital's rule, evalutate; LIM as x->0 e^x +cos x / e^x + sin x


I'm at LIM x->0 e^x+cosx / e^x +sinx but now I at a lost as to how to proceed.

  • calculus -

    Who need's L'Hospital's Rule?
    e^x + cosx --> 1 + 1 = 2
    e^x + sinx --> 1 + 0 = 1

    answer: 2/1 = 2

    You only need L'Hospital's Rule when you wind up with 0/0 or ∞/∞

    Unless the problem has a typo . . .
