Consider 'x' to be a variable. What is the derivative of 12x^4 + 10x^3 - 5x^2 + 16 with respect to x?
48x^3 + 30x^2 - 10x


Consider 'x' to be a variable. What is the integral of 18x^2 - 10x + 3 with respect to x? Pick the most correct solution.

6x^3 - 5x^2 + 3x + C


Suppose the integral was already performed on an equation. What is the simplified answer if you now take the integral from 0 to 1 for the following integrated equation:
8x^3 + 3x^2 - 4x + C
(Hint: closed interval [a=0, b=1])

I used the one in the post 28, which I believe was the refined version.

Great puzzle. Finally managed to solve it.

Lets be more considerate and open minded. It is infinitely possible that he could be of a higher order of intelligence and have the answer which we have been seeking.

Quite funny. Especially the sine and tan one.

Leo, if you want to learn a powerful yet extremely easy language, you should try Just Basic. And for web development, Run Basic. Just Basic is written in Small Talk and is completely free. Afterwards, you can try Liberty Basic for a minimal price.

I do not tend to use Python at all anymore.

The generation is what I would be most dependent upon. Currently, I would pick self-taught. That is because there are ~15 hours in a day where we are inactive, if we had no educational establishment to visit. 15 hours a day reading educational books, productive online articles et would most definitely make you more intelligent then school. In the past however, schools were more rigorous, there were fewer educational resources etc. However of course, combining both 4 hours of school and ~8 hours of self-teaching would make you an intelligent person of likes not seen by anyone. And as you know, if there were fewer officially educated persons (being educated from schools), we would have become extinct a long, long time ago, at a galaxy close, close at hand.

I do not believe that you can be active on this forum, while gaining the respect of being an intelligent man, without receiving a proper education from school (I would imply that in your youth, the sheer length of technological advancement would be fairly low, hence leaving no chance for being self-educated through the Internet (Moreover, Tim Berners Lee was probably not alive at that point). Books could have been a source of intelligence, however it would not fully equip you with the maturity received through school.

I seem to think that you are somewhat in proximity of 92 years of age. Considering that, with the fact that you have near 50000 posts related to advanced mathematical, scientific and humanities-related concepts, (plus about 5000 other communicative posts) in merely the time span from 2010-2013, you do not seem to have been at any point of time a lazy and/or bad student. As for resembling a human being, I cannot comment on physical appearance alone.

Unless you have an absentminded professor allowing you to cheat.

Hello Bob, Bobbym and Stefy. Been faring fairly well I suppose. The midterm exam is coming soon, so preparing has begun!

Hello everyone. As you may recall, I am Shivam and have been fairly inactive in the recent times (especially due to the whole university transfer process). I am now successfully placed in the Massachusetts Institute of Technology (Rogers Web Key still works in the US). Nowadays, I seem to have more time and plan to be more active on this forum.

#1548 Re: Coder's Corner » Is Anyone using BASIC Anymore? » 2012-11-23 01:56:19

My first programming language, when I was around 7, was essentially BASIC. Hence, I still love it.

Happy US Thanksgiving. In Canada we had it long ago. And happy Pearl Harbour day in advance.
