Determine if L'Hopital's rule applies in each case. Select all that apply.

lim_y-->0 3^y/y^2

lim_x-->pi (sin(3x))/(x-pi)

lim_t-->0 (t^2+3t)/(cosh(t)-1)

lim_z-->0 (e^(2z)-1)/e^z

lim_theta-->0 (arctan(theta))/(3(theta))

lim_x-->infinity (e^(-x))/(1+ln(x))

lim_x-->0+ (cot(x))/(ln(x))

lim_t-->infinity (ln(t))^2/t

we haven't exactly gone over L'Hopital's rule yet, but im tryin to do it early, any help on how you can tell whether the rule will work or not, thanks...
