Thus, the distance between two points in space obtained on actual measurement and by using distance formula is approximately the same. APPLICATION 1. This activity is useful in visualising the position of different points in space (coordinates of points). 2.The concept of position vectors can also be explained through this activity.

Components of Displacement Vectors: The Vectors ~i, ~j, and ~k The vectors ~i, ~j, and ~kare unit vectors, that is vectors of length 1, that point in the directions of the positive x-axis, y-axis, and z-axis, respectively. Using vector addition, we can write any vector as a sum of scalar multiples of~i, ~j, and ~k.

2 Parallel Vectors The operation of multiplying a vector by a scalar leads to the following de ni-tion: We say that two vectors ~u and ~v are parallel if and only if ~u = c~v for some non-zero scalar c: If c > 0 the two vectors point in the same direction. If c < 0; the two vectors point in opposite directions. Example 11.2.7

Center of mass and gravity 79 = r1 + m2 m1 +m2 the fraction of the distance that the cm is from r1 to r2 r2 − r1 the vector from r1 to r2.. so that the math agrees with common sense — the center of mass is on the line connecting the masses. If m2 m1, then the center of mass is near m2.Ifm1 m2, then the center of mass is near m1.Ifm1 = m2

is called the vector equation of the line (because it consists of vectors). We can also rewrite this as three separate equation: if ~v = hv 1;v 2;v 3i, then (x;y;z) is on the line if x = a+ tv 1 y = b+ tv 2 z = c+ tv 3 are satis ed by the same parameter t 2R. This is called the parametric equation of the line. See#1 below.

The cross product (or vector product) between two vectors A and B is written as AxB. The result of a cross-product is a new vector. We need to find its magnitude and direction. (See section 3-7 in the text for more review.) Magnitude: |AxB| = A B sinθ. Just like the dot product, θ is the angle between the vectors A and B when they are drawn ...

of Pearson correlation. Distance correlation is defined for 2 random variables X, Y (which can be vectors) as a weight or distance function applied to the difference between the joint characteristic function for (X,Y) and the product of the individual characteristic functions for X, Y. In practice it is estimated by computing the individual ...
