Hey,
Bit stuck on how to do this. Is it asking me to add up all the stationary points then come up with a value?
Thanks
The position of stationary point can be represent by vectors
$\displaystyle r_1 = (a_1,b_1,c_1,...,n_1) \text{ in } \mathbb R^n $
To add up all the N stationary points then come up with a value
$\displaystyle \sum_{i=1}^{N} r_i $ You add coordinates by coordinates. So you only get a "value" if you work in $\displaystyle \mathbb R $.
That's the way I understand the question but it is vague in my mind so could be anything else.
