# Math Help - Calculating exact coordinates of stationary points on a graph

1. ## Calculating exact coordinates of stationary points on a graph

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

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