language agnostic - How to learn reading complex math formulas? -

I'm a programmer, but when I'm facing complex mathematical formulas, I often get stuck.

Please suggest a good video lecture resource which teaches mathematical symbols, quantifiers etc. to teach.

This formula means something without reference. It seems that, in relation to E ^{p , in the form of partial derivative, p , which is negative from o to 1 to n The sum of the products of <__> p and w _{po , :}}

  def partial_of_E_wrt_y ( P): acc = 0 o in the range (1, not): acc = acc + delta [p] [o] * w [p] [o] return -acc   
 e, Y and δ superscript can be due to indexed usage, it also means that δ  o   p  w  po  may be a tensor product or It can be Author without using superscript index with respect to a relationship is like to have seen some texts learning a conference that I machine. If δ is not given any other interpretation, then it is possible that this means for it, which means that δ  o   p  = 1 if o = p, and 0 otherwise
