Thank you all for the help! It looks to me Ottawa University is the best option as of now. Although University of London is considerably cheaper, but I don't want to wait until 2014 to graduate when I can be done by early March with Ottawa. I've sent the information to my adviser to look over...

Hi billblack. Thanks for replying. I already tried that. Unfortunately, all I've found are either lower division classes which doesn't help, or the school only offers the degree as a whole and not individual classes. I have already taken enough hours at my school to graduate from there so that's...

Hi, I am currently looking for universities that offers Mathematics courses as an online or independent study course. I am only 2 courses short of graduation but unfortunately, so have my college funding. So if it's possible to take them online (which I believe is usually cheaper than on...

thank you tedjn, you helped me answer my questions and I understand the questions better now.

Oh you have no idea how glad I am to hear that I have finally at least gotten a few more questions on the right track and even two of them right. Now, I think I know where you're heading with number 2. I just have to prove that x/(x-2) < x+1 then I can conclude that f(x)=O(h(x)). With number...

*I failed horribly. First I had everything typed up and was about to post, but it failed because I accidentally typed in the wrong password. Then when I was retyping everything, I accidentally hit back and lost everything again. I am really frustrated now and I hope you won't mind my answers...

First off, thank you Tedjn for your reply. It really helped me understand the question better. 1. I didn't know about the Dijkstra's algorithm and that really helped me with question 1. 2. I read the definition of the big o notation and here's my second try: 10(x-1)(x-2)= O(x!)...

1. Explain how to find a shortest path between any given pair of vertices, given the length of edges connecting the vertices and the shortest distance between vertices (after doing the shortest-path calculation) So I am given a two matrices, as said one with length of edges connecting and the...

Oh, I see where you're going... (sinx)(secx)+1 <----since cosx*secx = cosx*1/cosx (sinx)(1/cosx)+1 [[(cosx)(cosx)-(sinx)(-sinx)]/(cosx)^2]+1 [(cos2x+sin2x)/cos2x]+1 (1/cos2x)+1? is the +1 supposed to stay?

1. Is there a value of b that will make... x+b, x<0 g(x) = < cosx, x=>0 continuous at x = 0? differentiable at x = 0? give reasons. 2. I'm not sure what are related equations for this. Limits? 3. So I try to find how to make it continuous at x = 0...

Ok, after reading DH's reply, I tried the question again and here's what I did. y=(sinx+cosx)1/cosx y'=(sinx+cosx)(-1/sinx)+(1/cosx)(-sinx+cosx) =cosx/-sinx + sinx/-sinx + cosx/cosx - sinx/cosx =cosx/-sinx - sinx/cosx does that seem simple enough for you guys? I wish I were given the...

1. As the title states, I need to fine d/dx(sinx+cosx)secx. 2. I am given pretty much most of the derivatives and trig functions. 3. Here's my attempt to solve the question: y=(sinx+cos)secx y'=(sinx+cosx)(secxtanx)+(secx)(cosx-sinx) =sinxsecxtanx+cosxsecxtanx+cosxsecx-sinxsecx...

Ah, I got it. Thanks a lot.

Yea i figured that out, so that mean the line of the derivative is just the slope of the original graph?

So the question asks me to use the following information to graph the function f over the closed interval [-2, 5] i) The graph of f is made of closed line segments joined end to end. ii) The graph starts at the point (-2, 3) ii) The derivative of f is the step function in the figure shown...
