Hello glisfton; welcome to the forum.

True, but I can say that with any language. Once you have the basics of programming under your belt, it's all just about syntax.

Thank-you; I just thought I needed some extra practive before the exams. After that, I should be much more relaxed... Anyways, I will post some more later.

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

I get 48x^3 + 30x^2 - 10x

Also:

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

I get  6x^3 - 5x^2 + 3x + C

Hi stapel; once again, I think he is simply trying to provide some practice problems for us to work on- rather then him being stuck on these subjects.

Some problems...one at a time.

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


I got 7.

Hi; I apologize for making you think I wanted to get this thread closed. I simply told you to make a slight change in the original post sice velocity is a vector.

#1411 Re: Exercises » Continuous velocity exercises » 2013-05-10 00:39:49

1 small thing by the way. Velocity is displacement over time.

#1412 Re: Exercises » Continuous velocity exercises » 2013-05-10 00:38:46

Since it is in the Exercises section, I would presume he meant for us to solve it for practice.

99% chance I am wrong...
Also, do not know Latex.
I =  ∫  infinity on top, 0 on bottom     (x^alpha)/(1+ √2x +x^2)dx

I am getting I = (√2pi)sin(alpha pi/4)  /  sin(alpha pi)

For which subject? Economics?

#1416 Re: This is Cool » I am about to make a new website » 2013-04-30 02:02:54

What is the website about? And are you coding it in PHP or ASP?

#1417 Re: Maths Teaching Resources » Some websites to go to » 2013-04-30 02:00:50

Onlinemathlearning is a great resource and contains the sciences as well.

#1418 Re: Help Me ! » Basic Integration » 2013-04-26 00:21:37

142 for me. But online tests are not too secure. One of them told me I have an IQ of 652.

Hello and welcome to the forum.

#1420 Re: Dark Discussions at Cafe Infinity » Biological Immortality. » 2013-04-24 03:54:26

Oh, extremely apologetic for bringing the topic up.

#1421 Re: Help Me ! » Basic Integration » 2013-04-24 03:53:20

That's amazing! You are a quick and young learner. Have you been tested for your IQ (just out of curiosity)?

#1422 Re: Help Me ! » Basic Integration » 2013-04-24 03:50:12

If I am correct, last week you posted after learning differentiation! Thats' quick.

#1424 Re: Help Me ! » Basic Integration » 2013-04-24 03:46:06

Thanks bobbym. Agnishom, you are doing integration before differentiation?!

#1425 Re: Help Me ! » Basic Integration » 2013-04-24 03:38:00

Integrating (0,3) gives me 3.
