The resultant of cross product of two vectors is a vector quantity. Vector cross product represents two vectors are orthogonal or perpendicular... View Article
The dot product of two unit vectors is always equal to zero. Therefore, if i and j are two unit vectors along x and y axes respectively, then... View Article
If i, j and k are unit vectors along x-axis, y-axis and z-axis respectively, then i.i = j.j = k.k = 1 And i.j = j.k = k.i = 0 Learn more... View Article
Distance is a scalar quantity and not a vector quantity as it has only magnitude. It means when object moves, its direction does not matter only... View Article
If we toss three coins, then total number of outcomes is equal to: 23 = 8 The sample space for three coins is given by: S = { ( H , H , H ) ,... View Article
To find the unit vector in the same direction of another vector, we have to divide the vector by its magnitude. For example, vector A = [3,6,1]... View Article
Dot product is evaluated for two vectors to find the scalar quantity. Hence, dot product of a vector and a scalar is not possible. Learn more... View Article
In Mathematics, we come across many formulas that we use to calculate a variety of quantities like area, perimeter, volume, etc., of different... View Article
Gravitational potential is not a vector quantity instead it is a scalar quantity and is a negative value. To calculate the value we need to... View Article
Trigonometric equations are those equations that includes trigonometry functions of a variable. These equations can be simple as well as complex.... View Article
Cross product is used to determine a vector that is orthogonal to the plane surface spanned by the two vectors. For example, in computational... View Article
Cross product of two vectors results in a vector itself, that is perpendicular to the two vectors and has both magnitude and direction. A x B =... View Article
In probability, binomial distribution gives the likelihood of different set of outcomes from an event. For example, to make a product the... View Article
Vectors are such quantities that have both magnitude and direction. For example, when a force is applied to an object that amount of force... View Article
Probability is the likelihood of an event occurring or happening. By the formula we know, if P(E) is the probability an event, then P(E) =... View Article
