• VECTOR FUNCTION

• POINTS TO BE NOTED: If curl F=0 then F is called an irrotational vector. If F is irrotational, then there exists a scalar point function ɸ such. GRADIENT OF A SCALAR * Let f(x,y,z) be a scalar point function of position defined in some region of space.

Then gradient of f is denoted by.

In general, a vector field is a function whose domain is a set of points in (or) and are scalar functions of two variables and are sometimes called scalar fields to.

The position vector of a point P(x, y) in two dimensions is xi + yj.

We will often the vector operator V to the scalar function f(x, y). Such a vector. It has meaning when it operates on a scalar function to produce the gradient of f: If curl F = 0 at a point P, then the fluid is free from rotations at P and F is. Scalar Field: A single-valued, real, scalar function f(P) which is defined at each point in a domain D. Note that the values of this function depend only on the. Jayesh Luhar.

QO SIRO HAMAR MINUSMA
For example, if we think of f as describing the temperature at a point x, ythen the gradient gives the direction in which the temperature is increasing most rapidly. Successfully reported this slideshow.

## VECTOR FUNCTION

If, say, we place a marble at some point x, y on this graph with zero initial force, its motion will trace out a path on the surface, and in fact it will choose the direction of steepest descent. Jayesh Luhar. Dhruv Patel.
