whew!! im sure wolfram could spit that out in like a nano second
wat a calculation !!!!!!!!!!!!!!!!!!!!!!!!!!!!!
correct!!!! just one small tip so you can save some time.....for example if you're having a test or exam the time is fixed and you want to this in the fastest possible way....try to multiply the first row with -2 , -4 and -3 at once and add to the other rows in one step...you'll save some precious moments....:D
i tend to divide off the other rows to get a -1 in the lead and then do the adding; but that can make for some scary fractions to deal with
if you have MATLAB on your computer I can show you how you can check the results. It'll take one minute to do it...:D
rref {{r1},{r2},{r3},{r4}} on the wolf
there r1 and such are your rows in a,b,c,d format
so tht is right :)))))))))))))))))) xD Thank you!!!!! XD i don't have matlab :/
hahah. that's nice :)
