Learn the inverse of a 3x3 matrix, how to solve a 3x3 matrix, and how to take the inverse of a matrix using row reduction method.
The inverse of the 3x3 matrix can be determined by calculating the determinant and matrix of cofactors and then dividing each term by determinant. Learn more at BYJU'S.
The first step is to calculate the determinant of the 3 * 3 matrix and then find its cofactors, minors, and adjoint and then include the results in the below-given inverse matrix formula. \[A^{-1} = 1/ |A | Adj (A)\] Inverse of 3 X 3 Matrix Example Let us solve the 3 X 3...
Y'=3ax^2+2bx+c Y''=6ax+2b 所以(6ax+2b)+(3ax^2+2bx+c)=2x^2+1 所以3a=2,6a+2b=0,2b+c=1 a=2/3,b=-2,c=4 故特解为Y=2/3x^3-2x^2+4x 原方程对应齐次方程的特征方程为r^2+r=0 r=-1或r=0 所以齐次方程的通解为y*=C1e^(-x)+C2 原方程的通解为y=C1e^(...
