State which of the following limits is "indeterminate". For each one that isn't indeterminate, state what the limit is, with a very brief explanation (about five words!). For each one that is indeterminate, find the limit if you can.
lim (2^x - x^2) as x -> infinity
lim (2^x - x^2) as x -> - infinity
lim (cos x)(ln x) as x -> 0+
lim (sin x)(ln x) as x -> 0+
lim (cos x)^(1/x) as x -> 0+
lim (sin x)^(1/x) as x -> 0+
lim (1/x)^(cos x) as x -> 0+
lim (1/x)^(sin x) as x -> 0+
lim (sin x)^(cos x) as x -> 0+
lim (cos x)^(cos x) as x -> 0+
lim (sin x)^(sin x) as x -> 0+
