How do you make the following matix into the identity matirx?

divide the first row by 2\n1 1/2\n1  -1\n\nSubtract the first row from the second row:\n1  1/2\n0  -3/2\n\nMutiply the second row by -2/3\n1  1/2\n0   1\n\nSubtract 1/2 of the second row from the first row:\n1  0\n0  1\n\nAnd you have the identity matrix

Assuming your matrix is of order nxn and you want submatrix of order mxm.\n\nThen there is (n-m+1)^2 submatrices.\n\nSo you can run this loop(Java code)\n\nfor(i=0;i==n-m;i++)\n{\nint k;\nfor(k=0;k==n-m;k++)\n{\nint p,q;\nfor(p=0;p<m;p++)\n{\nfor(q=0;q<m;q++)\n{\nprint("  ");\nprint(a[p][q]);\n}\nprintln();\n}\n}\n\n}\n\nTo print all the submatrices iterate over this procedure canging m from 1 to n.

If it's an identity, then you aren't allowed to move terms from one side to the other. Instead you must manipulate one side (leaving the other untouched) until it is identical to the other.\n\nSince the right side only depends on sinx (it has no cosx's), a good strategy would be to replace the cosx's on the left side.\n\nWe know (sinx)^2 + (cosx)^2 = 1, so\n(cosx)^2 = 1 - (sinx)^2\n\nSubstitute this for (cosx)^2 on the left side, then simplify by combining like terms. Voila - you'll have the right side.

There is a possible package at the bottom of the link.  But, why not just use some of the Matlab functions written by others and do it yourself?  Should be straightforward.

go to start>programs>accessories>system tools> charactor map,,,here you will see many symbols

Hold ALT and Type 0134.\n\n† Like this right???  †

It takes practice!  And its like a puzzle.  Just use the main trig identities as reference and a good math tutor.  Unfortunately, this place isn't the best place to ask that kind of question because we are limited by text explainations and trig identities need a lot more than that!

you can do it with Corel or Picture-It, or mainly any editor.\n\nAll you must do is: \n- open the file you want\n- select FILE / SAVE AS\n- type the same name (or other), and add ".ICO"\n\nIt should normally convert it.

you can go to "inset" then "symbol" and find it there. Or  alt - 0153

if u meant make x the subjct then tis is how u wd go abt it.\n\na^2 - ax = b^2 - bx\nax-bx=a^2 - b^2\nx(a-b)= a^2-b^2\nx        =(a^2-b^2)/(a-b)\nx        =[(a-b)(a+b)]/(a-b)    (using difference of two squares)\nx        =a+b

the 3 x 3 matrix A times the 3 x 3 matix B will yield a 3 x 3 matrix AB\n\nAB1,1 = (A1,1)(B1,1) + (A1,2)(B2,1) + (A1,3)(B3,1)\nAB1,1 = (-3)(-1) + (6)(0) + (2)(-5) = -7\n\nAB1,2 = (A1,1)(B1,2) + (A1,2)(B2,2) + (A1,3)(B3,2)\nAB1,2 = (-3)(8) + (6)(-3) + (2)(0) = -42\n\nAB2,1 = (A2,1)(B1,1) + (A2,2)(B2,1) + (A2,3)(B3,1)\nAB2,1 = (-4)(-1) + (8)(0) + (1)(-5) = -1\n\netc.

Copy, paste special, check the transpose box in the dialog box \n\nCheers\n\nDaz

I haven't tried it, but check out MatPy (linked below).  Another possibility is Numerical Python (also linked below).

http://www.anagramgenius.com/archive/algebr.html\n\nedit: sorry didn't answer your real question. I don't know of a program that does what you want, but it shouldn't be too hard to write it. \n\nEdit: Contact me at algebra@envisagecapital.com if you would like the solution. I wrote a quick program to do what you wanted.
