ok im going to try my best to express these problems because I dont really know how to get some of these symbols. If someone knows how to represent these:

infinity

radical

please tell me.

On to the problems (we need to find the limit):

1)

lim x / radical(x^2-x)

x-> -infinity

I basically tried multiplying the denom. to the denom and num to get rid of the radical. But then what?

2) I don't really understand these sin cos things (again find limit).

a)

lim (x-cosx)/x

x-> infinity

b)

lim 1/(2x+sinx)

x-> infinity

c)

lim cos(1/x)

x-> infinity

d)

lim (sin2x)/x

x-> infinity

I don't need all of these to be done, just choose which one u think is the easiest to explain and explain the best u can to me. thank you.
