1. ## large derivative

Can someone give the derivative of the equation below.

2. The trouble I am having with this is that your derivative isn't picking out a specific value of "i."

Yes the derivative when i=k is easily obtained. However I need the complete system of solutions. I forgot to mention though that the derivative needs to be zero. To be precise the vector of derivatives need to equal a empty vector, see below.

If I'm understanding you correctly then what you need to do is take the derivative for i = k, where k is at the moment undefined. Then your vector components will be in terms of the index k as k runs from 1 to m.

Thanks, your hint helped me solve it.
