- Reducing 2x4 matrix to row-echelon form - Math Help Forum
the answer for row-echelon form is [4-3i 4-3i 5-10i 8-11i 0 0 -10+10i -3+11i] and for reduced row echelon form is [1 1 0 1 6+0 7i 0 0 1 0 7-0 4i] i cant figure out what operations to use to get the answers the exercise says to use an algorithm By the way i came across this problem in my problem sheet book
- Row Column space and reduced row echelon form. - Math Help Forum
Hello, i have a problem that asks me to put in reduced row echelon form and I have no clue how to even begin Let A be a 4X5 matrix If a1,a2,a4 are linearly independent and a3=a1-3a2 a5=a1-2a2-3a4 determine the reduced row echelon form of A Any help is greatly appreeciated Thank You
- How many types of 2x2 matrices are there in reduced row-echelon form . . .
There are two 2x2 matrices of the same type that are in reduced row echelon form The first is the zero matrix 0 0 0 0 The second is the matrix of the form: 1 0 0 1 Is this correct, or am I misunderstanding the question? Thanks for your help
- Proof with reduced residue systems | Math Help Forum
It should be clear that the numbers \{r_1^k,\hdots,r_n^k\} form a reduced system if and only if no two of them are congruent \mod m - i e if and only if the map f: r \mapsto r^k is a bijection So it suffices to show that this map is invertible
- Would this be a correct reason for why row reduction method gives . . .
the columns containing the pivot entries of the row reduced matrix correspond to the column vectors of the matrix that are linearly independent,because every column of the row reduced matrix can be expressed as the linear combinations of columns containing pivot entries that means they are of the form Ax=b,where x are the coefficients of linear

- [SOLVED] another primitive root problem | Math Help Forum
form a reduced residue system (mod n) Using the previous result, show that if n has a primitive root, then n has exactly \phi(\phi(n)) primitive roots (Hint: Decide which powers of g give the primitive roots of n )
- Augmented Matrix in Calculator, TI-83 | Math Help Forum
I can get a solution on my calculator by just puting the augmented matrix in row-reduced echelon form When you reduce it to that form, you end up with many solutions The solution in the book is unique, x=2, y=-1, and z=3 Just plug it into any calculator and put it in row reduced echelon form and see what you get
- Solutions of Ax = 0 in parametric vector form | Math Help Forum
Describe all solutions to Ax = 0 in parametric vector form, where A is row equivalent to the given matrix: My thoughts so far: I know that when two matrices are "row equivalent" it means that one of them can be changed to the other by doing row operations
- Intersections of hyperplanes | Math Help Forum
Now just get this to reduced row form and you will have three free variables and the solution will have three vectors that make up your surface in 4d space You can use this in \mathbb{R}^n for any n \in \mathbb{Z}^{+} You will get no solution if the 2nd row is all 0's except for the last entry I hope this helps
