Hi,

Usuallt I am using Maple under windows xp . However my friend is using Maple 11 on MAC.

Just curious, dose the Maple on MAC has Classical Worksheet? because I want to type "pretty and proper" command....

the normal Maple has a problem with the font.....even if i change the font and the bold or itlaz, when i press "enter", the new line change back to 2d input....

Thanks

Hi,

I have a matrix

A:=<<1,-3,2>|<-2,6,-4>|<2,-1,5>|<3,1,8>|<-1,-7,-4>>;

how do I find a basis of im(A)?

Thanks

hi

i am doing a multiple integal integration from one of my tutorial sheet

Given D is the triangular region whose vertices are (0, 0), (Pi,0), (Pi,Pi), find

Int(Int(x*cos(x+y),x),y);

then I worked out something like

Hi

I founda something strange here:

diff(y(x),x$2)+4*y(x)=cos(2*x);

dsolve(%,y(x));

y(x) = sin(2*x)*_C2+cos(2*x)*_C1+1/8*cos(2*x)+1/4*sin(2*x)*x

that's the answer maple give me when i run it for the first time

take a look at the two cos(2*x) tern?

shouldnt that be just ONE constant times it?

ok then if you run it again

somtimes it can collect them together give you single cos(2*x) term with ONE constant
