I wouldn't recommend doing what I'm doing with my wiki. It takes so much time to write and draw graphs by hand that it's extremely inefficient if you think on good grades. The current state of my wiki is pre-calculus up to critical points for multivariable functions. I skipped integration for...

Bear in mind that courses often skip chapters and a lot of details.

the link is in the message, the first line. I wrote it.

http://appliedscience.byethost7.com/index.php/Main_Page This is what I'm doing. I'm writing a lot because that's how it works. To explain concepts with words is how I approach it. I've found that once you have the concept, calculations are the easiest part. This is the complete opposite of...

A learning disability would manifest itself in memory issues, writing issues and/or reading issues.

That's one of the reasons I decided to quit. I was always feeling that I was studying to pass on exams, never to learn properly. One way to think on problems is to reverse engineer questions. Think "What if this piece of information was changed? What if it was absent? They say that the...

I have decided to learn calculus, linear algebra, numerical methods, all by myself. I did fail all those at university multiple times. So many times that I've lost count. What I am doing is writing a wiki site. The first thing that I decided to do was to follow intuition and to have as many...

https://www.youtube.com/channel/UCmFHyfdsyryhf7PYQX2j-Pg I didn't put her channel because she doesn't record anything in english.

There is a brazilian lady that created a youtube channel with tips to succeed in local admission exams. She is focused on high competition, such as engineering (she is one) and meds (she passed by studying 3 months prior then dropped out in the first month). She skipped MA and went from BC...

I hope I can make this question clear enough. When we have a function such as f(x) = 1/x and calculate the side limits at x = 0, the right side goes to positive infinity. The left side goes to negative infinity. In calculus we are pluggin in values closer and closer to zero and seeing what the...

I'm studying calculus alone with textbooks. The part about moving the graphs to the right or to the left struck me because they just have a list of rules, properties and make you relate the graph with the corresponding equation. I know what is the rate of change and I thought I could do better...

Return later for me = years later. I can't put all the blame on the educational system, but I felt that almost everyone is driven by grades and sometimes having close to panic attacks or depression because people think that grades are everything to progress in the field / in the academy.

I was enrolled in meteorology but after so many failures, low grades, I decided to drop out. Some friends of mine who were admitted in the same year as me loved the field so much that they are already doing their PhD, in some cases abroad. For a long time I've been day dreaming about computer...

Some functions have straight foward integrals, but they get complicated if you take the inverse of it. 1/f(x) for instance. The primitive of 1/x is ln(x). In this case it's easy to check that the integral of 1/x or ln(x) from 1 to infinite diverges. ##\int_1^\infty (\ln(x))^n dx## If n = 0, I...

Teacher didn't specify. For some reason he thought it would be a good idea to give everyone 15 minutes to solve it last week. Solving it would give up to +1 point in the next exam.
