Q
Trap Rule - how to use the sigma section
A
Top of Sigma is n-1 (n being number of traps).
then x_i = i * width of trap
2
Q
Partial Derivative Notation
A
Right to left when doing it with the funny b notation
otherwise it’s as expected
just manually expand it
3
Q
Stationary Points Multivariable
A
D = fxx*fyy-(fxy)^2
if D>0 and fxx>0, local minima
if D>0 and fxx<0, local maxima
Saddle point when D<0
Inconclusive when D=0
