How to simplify a 3x3 matrix
WebFeb 23, 2024 · So I have to consider all the lines and solve the corresponding system to find the result. Moreover, since the eigenvalues are complex and coniugated, I think that it's enough this matrix to find the solution. What do you think about that? Any hint to simplify the finding of $\mathbf v$ and $\mathbf w$? Thank you very much. Webin non system cases, think about if you have just y = mx+b or y equals a number. if you have a number instead of y (and m of course) you can solve for x, while having y there makes it only so you can find a function you can graph. Let …

WebApr 19, 2024 · For a 3 × 3 matrix, the coefficients of the characteristic polynomial are 1, − tr ( X), tr 2 ( X) − tr ( X 2) 2, − det ( X) which could be easier to compute. In many exercises, a solution can be found by means of the rational root theorem. In the case of three equal values on the main diagonal, you might as well have solved for λ − 1.
