    Exclamation LiMiTs

    \lim_{x\rightarrow 0}\frac{sin^2x-x^2cosx}{x^3tanx}

    \lim_{x\rightarrow \infty}\frac{2^{x+1}+3^{x+1}}{2^x+3^x}

    In the second one how can i change the x\rightarrow \infty

    The answer is that you should not.

    It is just \frac{6\left(\frac{2}{3}\right)^x+3}\frac{\left( \frac{2}{ 3}\right)^x+1}

    What do you mean?

    That is just basic algebra. Divide by 3^x.

    There is no reason to try limits if one can't do algebra.
