10). If you chose v1 = -1, you would get the vector V' = (-1, -0.3), which points in the opposite direction of the first solution. These are the only two directions in the two-dimensional plane perpendicular to the given vector. You can scale the new vector to whatever magnitude...
In C++, Vectors are called dynamic arrays that can automatically resize themselves when an item is inserted or removed, with its storage being controlled automatically by the container. Vector items are kept in adjacent storage, which is easy to access and traverse with the help of iterators. Mo...
A unit vector in physics is an object that has a magnitude of 1. They are used to represent a direction. How do you write unit vectors? Any vector has a corresponding unit vector. The unit vector can be written as the vector divided by its magnitude. How do you find the unit vector...
HowStuffWorks has been explaining how things work to curious minds since 1998. Providing factual, unbiased content that's fun to read and makes difficult topics easy to understand.
Learn how to find the magnitude of a vector. Then, using a vector's direction and magnitude, learn how to create a vector and magnitude graph with...
Could you suggest a easy and understandable way to find the augmenting path?UPDATE #1:My BFS function:template <class T> vector<Vertex<T> *> Graph<T>::bfs(T source) const { vector<Vertex<T> *> path; queue<Vertex<T> *> q; Vertex<T> * v = ...
Finding sum of vector elements Tofind the sum of the elements, we can useaccumulate() functionwhich is defined in<numeric>header in C++ standard template library. It accepts the range of the iterators in which we have to find the sum of the elements; it also accepts a third parameter whic...
How to find the normal of two vectors?Cross product in Vectors:This problem involves finding the vector which is perpendicular to any two given vectors. The idea is to use the concept of vector cross product which results in a vector that is perpendicular to each of the individual vectors....
Given two vector spaces, V and W, they will be orthogonal complements if every vector in V is orthogonal to every vector in W and vice versa. The orthogonal complement of a subspace V is denoted by V⊥. It is proved that V and V⊥ are complementary in E....
Finding largest element of a vector Tofind a largest or maximum element of a vector, we can use*max_element() functionwhich is defined in<algorithm>header. It accepts a range of iterators from which we have to find the maximum / largest element and returns the iterator pointing the maximum...
