The discussion centers on using matrix determinants to calculate areas in higher dimensions, specifically addressing the challenge of finding the area of a plane suspended in space. In two dimensions, the area of a triangle or parallelogram can be determined using a matrix determinant composed of unity, x coefficients, and y coefficients. In three dimensions, while the matrix composed of x, y, and z coefficients yields volume, the focus remains on extending the area calculation to higher dimensions. The problem presented involves optimizing the placement of a triangular sheet on a rectangular table to achieve maximum area coverage.
PREREQUISITESMathematicians, geometry enthusiasts, and students studying linear algebra or optimization problems will benefit from this discussion, particularly those interested in applying matrix theory to real-world spatial challenges.
It's all explained here:vin300 said:It is possible to find area of triangle or parallelogram in euclidean by using matrix determinant composed of unity, x coeffs and y coeffs in row1,2,3 respectively. Is it possible to do that in higher dimensions as well although it may be not as simple as in 2D case. In 3d matrix composed of x,y,z would instead give volume but I am looking for area of a plane suspended in space.
