One may always apply a sequence of row operations and column operations of a n × n n × n matrix A A to arrive at Ir ⊕0t I r ⊕ 0 t where r r is the rank of the matrix and t t is the dimension of its kernel. For a more in-depth explanation, see this answer. – walkar. Oct 9, 2015 at 13:42.The easiest thing to think about in my head from here, is that we know how elementary operations affect the determinant. Swapping rows negates the determinant, scaling rows scales it, and adding rows doesn't affect it. So for instance, we can multiply the bottom row of this matrix by $-x$ to get that $$ \frac{1}{-x}\begin{vmatrix} x^2 & x ...Step-by-step solution. 100% (9 ratings) for this solution. Step 1 of 4. Using elementary row operations, we will try to get the matrix into a form whose determinant is more easily found, i.e. the identity matrix or a triangular matrix. ? -3 times the first row was added to the second row.To find the area under a curve using Excel, list the x-axis and y-axis values in columns A and B, respectively. Then, type the trapezoidal formula into the top row of column C, and copy the formula to all the rows in that column. Finally, d...
