| Hello Daniel, I need to find x values which can be obtained by solving the roots of the 8 degree polynomial in mathematica. I know that most of these problems are solved by numerical method such as Newtons' method. But is there any general solution... |
| This is a matrix of the homogeneous equation x'=Ax, and I want to find it's eigenvectors. here, I have defective eigenvalues with defect p and -p. I should find two linearly independent vectors which satisfy these equations: v0=(A+ lambda I)^2 =0, ... |
| Hi, Could you please help me to find problems in the following attachment? I want to find the coefficients (a1, b1, c1...).First, I wrote transformed governing equations (PDE to ODE), and then I imposed boundary and initial conditions by aid of... |
| Thanks Bill, I solved the error with your guide. :) |
