Thanks for the reply. Using the substitution, I got the correct answer (you base it off of the equality in 1) or something). But I can't figure out how to use integrals to solve integrals! The second part to the question is to use the PIF to solve 2)...when the integral of 2) is multiplied...

Homework Statement Use 1) \frac{1}{2\pi}\int\limits_{-\pi}^{\pi} \frac{r_0^2 - r^2}{r_0^2 - 2rr_0cos(\theta-t) + r^2} dt = 1 to compute the integral: 2) \int\limits_{-\pi}^{\pi} \left[1 - acos(x) \right]^{-1} dx for 0<a<1 [/itex]. The Attempt at a Solution I looked on Wolfram...

I got it. \bibliographystyle{acm} \bibliography{radiodeers} \nocite{*} However, I just get a () with in-text citations \citep{humans} --> ()

Bibtex: formating help! In my references, I want: Emanuel, Kerry A. The dependence of hurricane intensity on climate. Nature, 326:483–485, 1987. <GOOD! Emanuel, K. A. The dependence of hurricane intensity on climate. Nature, 326:483–485, 1987. <OR THIS, I WANT! Basically, I just want...

Thanks for both of your help. Thanks so much! Since a=c=0, I'm left with p(x) = 1 + x2 So the basis is 1, x2 which is the spanning set. I really appreciate it, so much.

Homework Statement Let W be the subset of all P3 defined by W={p(x) in P3: p(1)=p(-1) and p(2)=p(-2)} Show that W is a subspace of P3, and find a spanning set for W. Homework Equations The Attempt at a Solution This is homework we can correct. I've attached my work. The...

oops sorry about that, I meant "subspace of F[a,b]" F is the matrix with vectors a and b? :|

Thanks for your reply! Unfortunately F wasn't given any particular properties

Homework Statement Determine which of the following sets of functions are subsets of F[a,b] a) All functions f in F[a,b] for which f(a) = 0 b) All functions f in F[a,b] for which f(a) = 1 The Attempt at a Solution Ok so I am just learning about vector subspaces. After reading the...

Sorry, I realize there is a math & science software forum.

Homework Statement I need to create a function for scilab which adds a row of zeros to the right of an nxn matrix, a. I also have to add a row of 6's at the bottom but I think i have that part down. Homework Equations I think ones(,) is supposed to help? The Attempt at a Solution...

Thanks, I totally forgot about tension U: So I can solve for T and get mg=qE cot(θ) which gets me the right answer! Thanks so so much :)

Homework Statement Two identical spheres with mass m are hung from silk thread with length L. Each sphere has the same charge, so q1=q2=q. The radius of each sphere is very small compared to the distance between the two spheres, so they may be treated as point charges. Show that if the angle...
