the square of the hypotenuse (the longest side) is equal to the sum of squares of the other two sides. To calculate the modulus of vector r, we know that r has a horizontal length of 4 and a vertical length of 3. Therefore,
Definition: The convex hull of a set S is the intersection of all convex sets that contain S_{1} and is denoted \operatorname{conv} S. Definition: A vector \mathbf{v} is a convex combination of vectors \mathbf{v}_{1}, \ldots, \mathbf{v}_{m} if \mathbf{v}=\alpha_{1} \math...
when you rundie * die, R lines up the twodievectors and then multiplies the first element of vector 1 by the first element of vector 2. It then multiplies the second element of vector 1 by the second element of vector 2, and so...
