(attachment below)

Answer 1

I know (according to other people) it is supposed to be 0 to 1 and 0 to t - but I do not understand how they concluded that.

Answer 2

are there no constraints or conditions given got G(x,y) ?

Answer 3

@amistre64 G(x,y) has to be within the triangle

Answer 4

oh, I should have written that down; (0,0), (1,1), and (0,1)

Answer 5

dx = 0 to a
dy = L to b

Answer 6

My bad

Answer 7

consider how we move across the domain D

as we move x from 0 to a, y moves from L to b

Answer 8

or since ds dt order, ds is from 0 to L, and dt is from 0 to b

Answer 9

what is L in this case? The length?

Answer 10

L is the line that bounds the Domian
