With this application you may: 1) Check if two vectors form a base of R2. 2) Check if three vectors form a base of R3. 3) Check if four vectors form a base of R4. 4) Write rational numbers as fractions (in case that you want that a component of the vector to be a rational number). 5) See a detailed and mathematical description of the steps that led to that result. When you check if two vectors form a base of R2, the application will check if those vectors are parallel. When you check if three
