can someone please help me with this, I've been having trouble with it.

C(T)= 2t/(t+3)^2

find the maximum?

thanks

Do you know how to find the derivative of the function? If so then check when the slope is equal to 0.
To find the derivative use the (f'(x)g(x) - f(x)g'(x))/(g(x)^2)
 
If you've "been having trouble with it", then you must have tried something! What have you tried? Exactly where are you having trouble?
 

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...
