### Re: Perhaps some programming shall I seek...

I started out programming my TI-83 calculator. I then moved on to BSL, a "toy" language for the game Oni, that is near identical to C, then I made a jump to asm, THEN I finally took a class in C++.

### Re: Project Euler

I'm stuck on number 10. Both methods of prime number generation I have seem to give the same exact answer, 1179908154 Which is regarded as wrong. My "solution": /*The sum of the primes below 10 is 2 + 3 + 5 + 7 = 17. Find the sum of all the primes below two million.*/ #include <iostream> #...

### Re: Homework Check: Calculus, Integration

2. Yes, there is. The teacher requires us to state the rule number we used from the book, for ease of correction. What Nitrodon means is you can just use integration by parts and substitution to solve the integral. What would u be equal to? if u = sqrt(x^2 - 1), then I would be left with something ...

### Re: Homework Check: Calculus, Integration

You carelessly replaced "du" with "dx" at one point. As a result, you got the wrong answer. Also, there's no need to use a list of integrals (or whatever you took rules 60 and 40 from) for that problem. 1. Damnit. Now I have to go through again. Thanks. :) ...joy, this means I'l...

### Homework Check: Calculus, Integration

Look here on my wikipedia userpage, because converting all the work for these forums screwed over the formatting. http://en.wikipedia.org/wiki/User_talk:Gumby701/calc The basic problem is \int x^5 \sqrt{{x^2}-1} dx My answer: \frac{x({x^3}+ 1)(x^2-1)^{3/2}}{7} - \frac{\ln |x + \sqrt{...

### Re: "Floor Tiles" Discussion

I do the same too (step on with one foot, step on with the other.

I used to be really bad when I was younger about equal touchings and stuff, but I've learned to stop doing that. Hell, I've learned to ignore a lot of my OCD urgings, or else I would waste so much of my time...

### Re: "Neutrality Schmeutrality" discussion

The solution: use wiki code. :) Template for displaying a different number of words depending on the local hour. (I would do by second, but I have no idea how to parse the ISO date stamp in wikicode. <includeonly> {{#switch:{{{{LOCALHOUR}}}} |0=even |1=odd odd |2=even |3=odd odd |4=even ... |23=odd ...

### Re: Traveling across a square

Wow, I think about this one all the time. xkcd related places are really creepy deja vu for me. Basically, I think of it in terms of a velocity. For my example, 1m by 1m square, you move at 1m/s If you use "taxicab" movement, it takes you 2 seconds to do, correct? Even if you keep making t...
