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 ...

If I assume bottom left corner of the triangle as (0,0) on the wall then I can find other 2 coordinates of the triangle based on that (3 known coordinates), how can I use information from the other triangles to find the homography matrix. computer-vision transform transformation homograph...
So, if you happen to know that the U you are encountering do not lie on the entire 5D space, but only in a small 3D subspace of it, then, you can indeed expect to have that pseudo inverse working (that is, btw what SVD is. Finding actually relevant subspace). But if U ...
Matrix multiplication is the product of two matrices, which results in a single matrix. Visit BYJU’S to learn how to multiply two matrices, formulas, properties with many solved examples.
Factors of a number are those values that divide the original number evenly without leaving any remainder. Factors of 4 are 1,2 and 4. Find the factors of number using prime factorisation with examples at BYJU’S.

Many students have difficulty finding the distance between two points on a straight line, it is more challenging for them when they have to find the distance between two points along a curve. This article, by the way of an example problem will show how
The inverse of a matrix is the matrix that, when multiplied by the original matrix, produces the identity matrix.The inverse of a matrix exists only if the matrix is non-singular, that is, if the determinant is not 0. We can simply find the inverse of a square matrix using the ...
