L1.3 - Unconstrained optimization of quadratic functions

[@micahlingle1060]

At 2:46 when you write "df'(x)", is that intentional? Does that simply mean "f'(x)" ( == df/dx)?

Could you tell me the textbook you recommend for this kind of contents?

I don't get why dxT*Q*x transposed equals to xT*qT*dx

[@aa4cc]

They are both scalars. And a scalar is equal to its transpose.
And a transpose of a product is equal to the product of transposes in the opposite order.
