Hey mate its ok, I worked it out. Thanks anyway

Thanks for your reply and thanks for having a look. Gamma was meant to be $$\Gamma$$ (sorry about that) I have copied what is above directly from the book. Do you know how to get from j to the next step ? Thanks

Does anyone know why latex is not working on the first part of equation?

Homework Statement I am working through some maths to deepen my understanding of a topic we have learned about. However I am not sure what the author has done and I have copied below the chunk I am stuck on. I would be extremely grateful if someone could just briefly explain what is going on...

is my method right for doing it into steps please?

so for the first leg x:0 to 1 y: 0 to x 2nd leg x:1 to 2 y:1 to -x+2 is that right?

so for the second leg is it x goes from 1 to 2 and y goes from 1 to -x+2?

ok, it is y=-x+2

Thank you for the good explanation.

Evaluate ∫∫(x^2 + y^2)dx dy over the region enclosed within R (0,0), (2,0) and (1,1). I am not asking someone to do the problem but to just verify, have I got the limits right? I split it up into 2 legs for the first leg integrate from , x: 0→1 and y :0→x for the...

When multiplying cosets, can you just quite simply multiply them together? Our teacher said something about their could be a potential problem? What could the problem be?

ok thanks

Just by looking at the cayley table of a group and looking at its subgroups, is their a theorem or something which tells you if the right and left cosets are equal? I have question to do and I would love to half the workload by not having to to work out the same thing twice. Thanks

x1 1 1 0 0 x2 0 0 1 1 x3 = 1 + -1 + 0 + 0 Each of these numbers in vertical form are meant to be x4 0 0 1 -1 vectors Where do these coefficients come from...

Ok thanks. Part of the problem is I do not know how to revise it. I did really well in analysis and I learned it by proving theorems, should I apply the same technique to linear?
