When calculating limits by using taylor series is there any easy way to know how many elements that should be included in the taylor series?

if I have

[tex] \lim_{x\rightarrow\zero} \frac{exp(x-x^2)-Cos2x-Ln(1+x+2x^2)}{x^3} [/tex]

How do I know many terms to include in the taylors series for the exponent, cos and logaritm functions?? Should I include all terms that contains a [tex]x^3[/tex]??
