Why can't she watch the short videos from ed.ted.com, then read English on a daily basis? Source: almost 4 years ago

I tell them they need to watch short videos, say from ed.ted.com, then do 30 mins of reading English, reading out loud to themselves. I say do this daily and ask about words unknown, or contexts, and see what happens. The ones who really want to learn come back speaking better english, after a while of course. Those that don't bother helping themselves make little to no progress. I lay it out from the start that... Source: about 4 years ago

Https://mathworld.wolfram.com/ is great for defining things. Their explanation as to why square roots are only positive (or why we only use the principal square root even though its plausible that we could use negative and positive) is my favorite. Hopefully I stated that correctly but in case not here's the link https://mathworld.wolfram.com/PrincipalSquareRoot.html. Source: almost 3 years ago

Just to add to what’ already been said, Bessel functions are typically considered to be special functions. This term describes functions that aren’t elementary, but have a lot og uses/show up in lots of contexts, and generally are considered to have “nice” properties. Source: over 3 years ago

I think you would benefit greatly from reading a section and highlighting concepts you don't understand and look them up in Mathworld, it will help with definitions of specific things. After each section it may also help to look at implementations of these in the programming language you are using whether it be python with tensorflow or C etc. Source: about 4 years ago
