Assuming the result lim x approaches 0 (sinx)/(x) = 1, evalute
1) lim x approaches 0 (1-cosx)/(x)
2) lim x approaches 0 (1-cosx)(x^2)
3) lim x approaches 0 (tanx-sinx)/(x^3)
Can anyone help, I would appreciate it. My trig is horrible.

Remember that you can use l-hopitals rule for indeterminate forms. Have you tried that?
Here's an example, number 1 should be easy enough for you if you apply l-hopitals rule, here is the second limit:
As you can see, there isn't much trig involved in that one. It's just l-hopitals rule.
