The gradient, at any point P:(x, y, z), of a scalar point function Φ(x, y, z) is a vector that is normal to that level surface of Φ(x, y, z) that passes through point P. The magnitude of the gradient is equal to the rate of change of Φ (with respect to distance) in the direction of the normal to the level surface at point P.
Grad Φ, evaluated at a point P:(x0, y0, z0), is normal to the level surface Φ(x, y, z) = c passing through point P. The constant c is given by c = Φ(x0, y0, z0).
If you think of it as a hill, then the gradient points toward the top of the hill. With the same analogy, directional derivatives would tell the slope of the ground in a direction.
(-1.5,0) (1.5,0) what is the gradient?
Draw a tangent to the curve at the point where you need the gradient and find the gradient of the line by using gradient = up divided by across
well i am assunming you mean 'm' in linear graphs. it means the gradient in the linear equation y=mx+c.
A positive gradient goes uphill from left to right A negative gradient goes downhill from left to right
The gradient of a curve is the rate of change in the dependent variable relative to the independent variable.
Do you mean "down the concentration gradient"?
say what
A graded change in the magnitude of some physical quantity or dimension
Concentration gradient.
1. meaning of physical needs?
it used in our practical life.. for ex. in hills r in mountains
the gradient of a scalar function of any quantity is defined as a vector field having magnitude equal to the maximum space rate of change of the quantity and having a direction identical with the direction of displacement along which the rate of change is maximum.
If you think of it as a hill, then the gradient points toward the top of the hill. With the same analogy, directional derivatives would tell the slope of the ground in a direction.
What is the physical meaning of Operating Voltage of detector
The physical meaning of time constant is when your component stops functioning briefly
Pressure gradient is the rate of pressure change as you change position, not just the difference between the lowest pressure and the highest pressure, but how great (or small) the physical distance between them. Since it the pressure difference that make air flow (wind) the greater the pressure gradient, the greater the wind.
