The application for calculating matrices, determinants, and vectors is a very useful tool. It is designed for students and engineers who rely on matrix calculations in their studies or work. Using the necessary formulas, the program performs step-by-step calculations and provides a detailed solution. You can calculate matrices with dimensions up to 5x5 and vectors in 2D or 3D. Each calculator includes a brief theoretical explanation of the specific task. The application also features a random number generator to quickly create sample expressions with random numbers. The application perform following operations with matrices: • Matrix addition • Matrix subtraction • Matrix scalar multiplication • Matrix square • Matrix multiplication • Matrix transposition Determinant calculations: • Calculation of the determinant using the Sarrus method • Calculation of the determinant using the Laplace method Vector operations: • Vector Length • Vector coordinates by two points • Vectors addition • Vectors subtraction • Scalar and vector multiplication • Scalar product of vectors • Cross product of vectors • Mixed (scalar) triple product • Angle between two vectors • Projection of a vector onto another vector • Direction cosines • Collinear vectors • Orthogonal vectors • Coplanar vectors • Area of triangle formed by vectors • Area of a parallelogram formed by vectors • Volume of pyramid formed by vectors • Volume of a parallelepiped formed by vectors The application content is available in the following languages: English, French, German, Italian, Portuguese, Russian, Spanish, and Ukrainian. The application is being actively developed and supplemented with new calculators. Keep for updates!
