首先根据Vieta‘s Theorem可知: α+β+γ=1 αβ+βγ+γα=−3 αβγ=10 (i) u=−α+β+γ⇒u+2α=α+β+γ=1 于是,α=1−u2 因为α满足α3−α2−3α−10=0, 所以(1−u2)3−(1−u2)2−3(1−u2)−10=0 化简可得, u3−u2−13u+93=0 上述方程就是以...

This is the graph of the polynomial p(x) = 0.9x4 + 0.4x3 − 6.49x2 + 7.244x − 2.112.We aim to find the "roots", which are the x-values that give us 0 when substituted. They are represented by the x-axis intersects.

The roots of the characteristic polynomial are the eigenvalues of the matrix. Therefore, roots(poly(A)) and eig(A) return the same answer (up to roundoff error, ordering, and scaling). Roots Using Substitution Copy Code Copy Command You can solve polynomial equations involving trigonometric ...
知识点1:韦达定理(Vieta's formulas),也称为韦达方程(Vieta's equations),是关于多项式方程根与系数之间的重要定理。这个定理是由法国数学家弗朗索瓦·韦达(François Viète)在16世纪首先发现的。韦达定理给出了方程根与系数之间的关系。对于高阶多项式方程,韦达定理为我们提供了一种便捷的方式来求解方程的根与系数...
