Having problems with a few of these, thanks for any help in advance.
This one is to be answered in terms of the constants involved
lim ((3/h)-(3/a))/(h-a)
h->a
lim (cos(x)-2)/(sin(x))
x->0
lim ((1/(h+3)^2)-(1/9))/h
h->0
Thanks Again

The first can be easily found by recognising it as being the derivative evaluated at x = a of the function f(x) = 1/x ......
For the second, the limit is -oo since you have a form -1/0.
For the third, you should recognise it as being the derivative evaluated at x = 3 of the function f(x) = 1/x^2 ......
