comment Geometric calculation: two kneading discs
Do you know the exact geometry of 1 of the discs? or only the area? If you know the function describing the long edge of the discs then it shouldn't be too hard to come up with an answer

comment Detect values in array that are statistically inconsistent
Moreover, from the sentence "these values are sampled in less than 1 millisecond, and that what is being measured has no chance of changing so fast", I would think that using a low-pass filter doesn't need any additional assumptions

comment Detect values in array that are statistically inconsistent
For the general case, I agree with you, but I think, given the explanation of the OP, these options are both not necessarily statistically terrible. He mentions himself: "Glitches do happen and these need to be thrown out or the end result data may spike unnecessarily. It may be helpful to know that these values are sampled in less than 1 millisecond, and that what is being measured has no chance of changing so fast." So we are not looking at the tails of a normal distribution, we are really looking at spikes in the data which are easily recognized by thresholding

comment Lagrange Multipliers; two inequalities.
You are mixing two things here. You are looking for the extremum of $f(x,y,z)$ and all of a sudden you have constraints on a function $g(x,y,z)$. I think you should write $$g(x,y,z) \leq f(x,y,z) \leq h(x,y,z) $$ Then the equation for a constraint extremum becomes: $$\nabla f = \lambda \nabla g + \mu \nabla h $$ with $g(x,y,z)=c_1$ and $h(x,y,z)=c_2$

Nope, sorry. But since this is homework I think you will have to do with hints and pointers instead of full answers
