Step 5: Find the inverse of our matrix using the formula A−1=1det(A)⋅B. Vocabulary for How to Find the Inverse of a 3×3 Matrix Matrix: A matrix is an organized array of numerical data with a dimension of m×n, given the matrix has m rows and n columns. In this case, ...
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^(-x)+C2+2/3x^2-2x^2+4x ...

Numpy's array manipulation routines include arot90method, which gives 4 of the 24, but I'm clueless how to calculate the rest. My only idea is to convert the 3d array to a 2d matrix of co-ordinates, multiply by a rotation matrix, and convert back. But I'd rather work directly with...
