Bit stuck on how to do this. Is it asking me to add up all the stationary points then come up with a value?
The position of stationary point can be represent by vectors
To add up all the N stationary points then come up with a value
You add coordinates by coordinates. So you only get a "value" if you work in .
That's the way I understand the question but it is vague in my mind so could be anything else.
