1. ### Problem with integration

I am really new to the calculus field. I have a small problem in integration when it comes to finding the area under a curve when the curve passes beyond the negative side. Can anyone provide me some links where I can get some good knowledge about integration ? Thanks :smile:
2. ### Engineering acrreditation websites

hey guys, Are there any web sites that can give me engineering accreditation info about US and Canadian universities? For example like the ABET (http://www.abet.org/) Thanks a lot :smile:
3. ### How do I measure the irradiance of a particular wavelength?

thanks hi, Thanks alot guys, really helpful. Claude, yes as you have mentioned I am going to use cellophane (or glass paper). I've searched for 1 week in my country for colour filters and couldn't find any. Even to find a solar panel it was really difficult, but I managed to get a panel...
4. ### How do I measure the irradiance of a particular wavelength?

I am still a high school student and I want to do an experiment on a solar panel. I want filter out red light and then focus is it onto a solar panel and measure various intensities and how it relates to the variation of power output from the solar panel. For this I suppose I should measure the...
5. ### Are aero engineering and Aerospace engineering the same?

Ok thanks. I was a little confused with that.
6. ### Trinomial Expansion

anyone can help me? :(
7. ### Are aero engineering and Aerospace engineering the same?

I am a little confused with these two, are aero engineering and Aerospace engineering the same? Thank you
8. ### Testing Has anyone taken the SAT physics subject test?

Peterson I bought the Peterson's. That's the only book that I was able to find in my country for physics SAT test.
9. ### The Future of Sex?

Yuk Yuk, what load of crap is that? :yuck:
10. ### Kepler's third law

Hi Hi Thanks alot for replying. We finished orbital motion just 3 days ago and he gave us a work sheet with problems to solve. I think your correct, he approximated the orbits as circular to keep thinngs simple. The equation that I am using is 4pi^2r^3/GM r- radius of orbit M - mass of...
11. ### Kepler's third law

I don't know but in school I learnt it in a different way. I mean in school the Kepler's third law was thought as if all the orbits were circular. But according to the definition its all elleptical, and in the school equation we won't add the planets mass, but here...
12. ### Trinomial Expansion

I find it difficult to expand a trinomial using the formula method (factorial method) where you can find the coefficient of any term without expanding the whole trinomial. I can understand the binomial, but I can't do the trinomial using the general sigma notation method. Can someone please...
13. ### Testing Has anyone taken the SAT physics subject test?

thanks hi, Thanks alot. In mechanics in the IB they won't do angular momentum , angular acceleration and things. Did you see any questions from those too. By the way thanks alot for the links and advice, really appreciate it. :smile: Did you use the same guides too? Thanks alot
14. ### Testing Has anyone taken the SAT physics subject test?

Has anyone taken the physics test? I have never seen any model questions, but I just need to know whether the IB physics course will be enough to take the SAT physics. Thanks alot:smile:
15. ### Dative bond confusion (or coordinate bond)

I am a little confused with this. I know what a dative bond is, but the problem is when it comes to complex ions I do not understand. ok now for example NH_3 + H^+ = NH_4^+ So in this the lone pair of NH3 will fill the s- subshell of H and make it stable, but say in Cu^2^+ when this attracts...
16. ### How to mentaly get answers at once when given in powers?

Is there any method that you can calculate by mentaly and get answers mentaly when a number is given with a power. I mean for example say, 3^4 will be equal to 81. This is just a simple one. I mean now if a number is given like 6^12 then is there a method that you can get the answer by mental...
17. ### Where to learn coordinate gepmetry?

A little more advance Hi, Thanks alot for the site, but i want one that is a little more advance. I have done these parts. Thanks alot:smile:
18. ### Sereach for a subject

You look very interesting You look very interested in physics. Well try researching in something that you are sure like. I mean like in the field in which you are mostly the best.:smile:
19. ### Where to learn coordinate gepmetry?

I am currently learning about coordinate geometry. But I need to brush it up a little also. I want to know geometry about the straight line. Can anyone give me a website for this. i searched in the google but can't get any results that I need. Thanks alot.
20. ### I can't understand this in partial fractions

hi arildno, Uhh were you able to get anything? Well it's ok take your time, I am not in a hurry.
21. ### I can't understand this in partial fractions

Ok no problem. Realy appreciate your intrest in helping me. Can't believe, but realy you are great person. Thanks alot Hope I will find a solution.
22. ### I can't understand this in partial fractions

Well I am sort of like stuck. But I have to face these. TO be honest arildno I don't know that also. :cry: What am I to do? have any website that I can learn all these and come back to you?
23. ### I can't understand this in partial fractions

I am just in the A/L class. Just finished my Local O/Ls. I just swiched to the english medium now. I don't know, realy that teacher is too advance sort of. Even the other students also sort of get fedup of maths like. But I am trying to somehow keep up. He told us that there is a big gap between...
24. ### I can't understand this in partial fractions

I am sort of Sorry arildno :frown: I havn't learnt any of them. Will it be very difficult for me to learn it?:smile:
25. ### I can't understand this in partial fractions

you mean like |x|<1 right?
26. ### I can't understand this in partial fractions

Is this like the pascal trangle. I mean some what related to the binomial theorem?
27. ### I can't understand this in partial fractions

oh ya I see. Yep agreed.

Yep agreed
29. ### I can't understand this in partial fractions

Ya no problem at all.
30. ### I can't understand this in partial fractions

Oh I see. So this \lim_{N\to\infty}S_{N}=S is something about a limit. Realy great to learn about this. I didn't know about this. Actualy I haven't done this yet. Ok I get it now. ok arildno I get it upto here without any problem. Now my next step will be?
