Hey,

Just need to evaluate this limit, I know that the answer is 0, but I can't figure out how to prove it. Any help is greatly appreciated.

lim(x-0) of (sin(cosx-1))/x

Thanks.

Use L'Hopital's rule.
 
Oops, figured it out just after I posted... just multiply by (cosx-1)/(cosx-1)... sorry! :blushing: Somebody can delete the thread if they want...
 

Thread 'Finding the nth roots of a complex number'

There are two things I don't understand about this problem. First, when finding the nth root of a number, there should in theory be n solutions. However, the formula produces n+1 roots. Here is how. The first root is simply ##\left(r\right)^{\left(\frac{1}{n}\right)}##. Then you multiply this first root by n additional expressions given by the formula, as you go through k=0,1,...n-1. So you end up with n+1 roots, which cannot be correct. Let me illustrate what I mean. For this...
