    1. xT∇2L(x∗)x>0,,∀x∈C

      Why is the Lagrangian evaluated at x^* but x evaluated across all x?

    2. C={x≠0:∇gi(x∗)Tx∇gi(x∗)Tx∇hi(x∗)Tx=0,i∈AS+,≤0,i∈AS0,=0,i=1,...,m

      broken set notation?

    3. zTH(x∗)z>0,∀x≠0

      Why is there a \forall x \neq 0 here?

    4. s.t.h(x)=0g(x)≤0x∈X⊂Rn \begin{aligned} \text{s.t.} &\mathbf{h}(\mathbf{x})=\mathbf{0} \\ &\mathbf{g}(\mathbf{x})\leq \mathbf{0} \\ &\mathbf{x}\in X \subset \mathbb{R}^ n \\  \end{aligned} The impact of the constraints is primarily felt through the feasible region which, as shown in the figures below, can drastically affect the location of the global minimum: As we can see the feasible region can either: change the location of the minimum, leave it unaffected or produce a minimum in an objective function which did not seem to have any. As we can have both equality and inequality constraints, we will consider these individually.

      missing image?

    5. 3. [ENTER DESCRIPTION]

      It'd be nice if this matched the mathematical notation above & was not choppy & blurry

    1. dimJi<q

      broken latex

    2. ykfixedk∈Jj

      broken latex

    3. ykfixedk∈Ji

      broken latex

    4. Ji⊂JjJi⊂JjJi\subset Jj)

      Shouldn't this be J_j \subset J_i?

    5. |NZ|,breakingtheconstraint.The|\mathcal{NZ}|, breaking the constraint. The -1$

      Missing $

    6. |NZ|

      Could be written \mathit{NZ} to avoid spacing between variables

    7. n∈0,Un⊂N

      this is flat-out wrong, check the lecture slides

    8. (must choose at least one reactor):

      must choose exactly one reactor*

    9. P

      should be lowercase p for consistency

    1. 17. Chemical potential of nitrogen along isotherms varying with pressure

      I plotted this using a thermodynamics library, I'm not sure why the point of intersection between the ideal and real chemical potentials seems to occur at much lower pressures than figure 16 shows above..

      The general shape and existence of a cross-over should be correct though

    1. E[X|Y=y]=∑xxfX,Y(x,y)

      I think this should be sum x*f_{X|Y} rather than f_{X,Y}

    2. E[X|Y=y]=∫∞−∞xfX,Y(x,y)dx

      This is wrong I think -> should be \int x*f_{X|Y} dx

    1. nA,0−nA(t)−knA(t)vTVR=dnAdt

      I believe this should have a tau in the accumulation term?
