Hello PhysicsForums, My previous posts here do a rather good job at illustrating my indecisiveness. Here's some background: I started uni in the fall of 2010. After applying to maths programs at many Canadian universities, and Economics at Norwegian ones, my choice fell on Economics at the...

You have a point, Mute. I can certainly see Mandarin being very useful in jobs other than academic ones. Mayonaise, that's partially why I initially favored Mandarin over more closely related languages like German. The fact that the culture (as well as the language) is further separated from...

I am aware that it's hard to learn, yes. I think that is why it, along with Japanese, appeals so much to me, compared to easier languages such as German. And you are correct to assume that I have some concept of tone from Norwegian. It is as you say still hard to learn, however. I fully intend...

Could I ask which field you're in? Thanks for the tips, guys.

I'm sure this has come up before, but I hope angling it in this specific manner helps justify the new post. I will be starting university this fall, and have decided I want to learn a third language (First being Norwegian, second being English.. Or the other way around. Equally fluent in both...

Homework Statement http://folk.uio.no/robinbj/gg/ggstart.pdf" I am supposed to find the area of the triangle PQD. The numbers given are the areas of the other triangles.Homework Equations A= \frac{1}{2} a b \sin{C} As well as Heron's formula, possibly? A= \sqrt{s(s-a)(s-b)(s-c)} where s =...

Medschool in Norway is like that. All of it.

I guess I could add that I'm also considering the University of Oslo in Norway. Anyone actually know whether or not they have an internationally respected Maths department?

Hiya, I'm currently applying to Canadian universities for an undergrad degree in Mathematics (Combined with Computer Science somehow). My first choice would be University of Toronto, but that costs beyond what I am able and willing to pay for an undergraduate degree as an international...

I don't have any first-hand experience yet, but I could share tips I've heard both here on the forums and elsewhere. I am applying to Canada in 2010 as well, though I will be majoring in Maths, not Physics. For undergraduate studies, from what I've gathered, it doesn't matter much where you...

Final calculations, then. 1/R(P) = 1/R + 1/R = 2/R --> R(P) = R/2 R(total) = R/2 + R = 3R/2 I(M) = V/R = V/(3R/2) = 2V/3R V(M) = I(M)R = 2V/3 Thus: V(P) = V/3 I(P) = V(P)/R = (V/3)/(R/2) = 2V/3R I(L) = I(N) = V/3R Then after the break: I(M) = V/2R V(M) = RI(M) = V/2 (Felt the need to...

Thank you so much for the help :) I get it now.. I think.

Hmm. Indeed. Would I be right in assuming that that parallel receives 1/4 the voltage, and lamp M the rest (since V = RI, and Vp = (R/2)(I/2)) ? If so, I get the following calculations So, first, if I want to find the total resistance in the parallel: 1/R(P) = 1/R + 1/R = 2/R = 1/(R/2)...

*facepalm* Yes, of course. And this exercise is from the sub-chapter before cross products, so I figured I'd try to do it the way they wanted me to do it. Thanks a lot :) Edit: Just to complete the solution: | c | = \sqrt{7^{2} + 10^{2} + 16^{2}} = \sqrt{405} =...
