When it comes to completing homework all they seem to care about is getting the right answer and being done with it. I mean I get it, physics is time intensive and we're all doing the same work for the same classes (me with some extra actually) . But if you don't want to actually put the work...

I will basically focus on 18th and 19th century, I got to know from the biographies of Max Planck and few other that there were no organized syllabus in Universities for studying. Students had to take classes that they could understand and it was less like a lecture and more like a private...

Hello all, Now I had graduated from high school, and I'd like to self-study (revisiting) high school mathematics and physics (not for exam). But recently I often saw ads for a local online course platform. Many of the platform's users have been admitted to top colleges, and get better score...

Hi, so I'm a first year undergraduate in engineering science. I guess my main question is, are all undergrad textbooks purposely convoluted to scare us from our degrees? Let me explain. I enjoy my lectures, I feel like the notes are very useful, but whenever my tutors or lecturers refer us to...

##\sum_{n=1}^\infty \frac {(sin 𝜶)^n}{2n} ## I apply the root test and i get ##\lim_{n \rightarrow +\infty} \frac {sin 𝜶}{2n^\frac 1 n} ## at this point i don't know how to treat the denominator.

## \sum_{n=1}^\infty (-1)^n \frac {log(n)}{e^n}## i take the absolute value and consider just ## \frac {log(n)}{e^n}## i check by computing the limit if the necessary condition for convergence is satisfied ##\lim_{n \rightarrow +\infty} \frac {log(n)}{e^n} =\lim_{n \rightarrow +\infty}...

It's 13 week plan. I need your feedback to improve it

Hi all, Forgive me if this post seems long, I tried to make it as short as possible by removing any unnecessary details, and leaving only the things needed. It would really mean so much to me if you would be able to read all of it to better understand my position, but if you're unable to read...
