An area of ground that tends evenly upward or downward.

‘I had to climb a small slope to get to the site.’;

A slope or incline.

Slopenoun

The degree to which a surface tends upward or downward.

‘The road has a very sharp downward slope at that point.’;

A rate of inclination or declination of a slope.

Slopenoun

(mathematics) The ratio of the vertical and horizontal distances between two points on a line; zero if the line is horizontal, undefined if it is vertical.

‘The slope of this line is 0.5’;

(calculus) Of a function y = f(x) or the graph of such a function, the rate of change of y with respect to x
that is, the amount by which y changes for a certain (often unit) change in x
equivalently, the inclination to the X axis of the tangent to the curve of the graph.

Slopenoun

(mathematics) The slope of the line tangent to a curve at a given point.

‘The slope of a parabola increases linearly with x.’;

(science) The rate at which a physical quantity increases or decreases relative to change in a given variable, especially distance.

Slopenoun

The angle a roof surface makes with the horizontal, expressed as a ratio of the units of vertical rise to the units of horizontal length (sometimes referred to as run).

‘The slope of an asphalt shingle roof system should be 4:12 or greater.’;

(analysis) A differential operator that maps each point of a scalar field to a vector pointed in the direction of the greatest rate of change of the scalar. Notation for a scalar field φ: ∇φ

Slopenoun

A person of Chinese or other East Asian descent.

Slopeverb

(intransitive) To tend steadily upward or downward.

‘The road slopes sharply down at that point.’;

Moving by steps; walking.

Slopeverb

(transitive) To form with a slope; to give an oblique or slanting direction to; to incline or slant.

‘to slope the ground in a garden;’; ‘to slope a piece of cloth in cutting a garment’;

Rising or descending by regular degrees of inclination.

Slopeverb

To try to move surreptitiously.

‘I sloped in through the back door, hoping my boss wouldn't see me.’;

Adapted for walking, as the feet of certain birds.

Slopeverb

(military) To hold a rifle at a slope with forearm perpendicular to the body in front holding the butt, the rifle resting on the shoulder.

‘The order was given to "slope arms".’;

Moving by steps; walking; as, gradient automata.

(obsolete) Sloping.

Rising or descending by regular degrees of inclination; as, the gradient line of a railroad.

(obsolete) slopingly

Adapted for walking, as the feet of certain birds.

Slopenoun

An oblique direction; a line or direction including from a horizontal line or direction; also, sometimes, an inclination, as of one line or surface to another.

Slopenoun

Any ground whose surface forms an angle with the plane of the horizon.

‘buildings the summit and slope of a hill.’; ‘Under the slopes of Pisgah.’;

Slopenoun

The part of a continent descending toward, and draining to, a particular ocean; as, the Pacific slope.

The rate of increase or decrease of a variable magnitude, or the curve which represents it; as, a thermometric gradient.

Sloping.

‘A bank not steep, but gently slope.’;

The variation of the concentration of a chemical substance in solution through some linear path; also called concentration gradient; - usually measured in concentration units per unit distance. Concentration gradients are created naturally, e.g. by the diffusion of a substance from a point of high concentration toward regions of lower concentration within a body of liquid; in laboratory techniques they may be made artificially.

In a sloping manner.

a graded change in the magnitude of some physical quantity or dimension

Slopeverb

To form with a slope; to give an oblique or slanting direction to; to direct obliquely; to incline; to slant; as, to slope the ground in a garden; to slope a piece of cloth in cutting a garment.

the property possessed by a line or surface that departs from the horizontal;

Slopeverb

To take an oblique direction; to be at an angle with the plane of the horizon; to incline; as, the ground slopes.

In vector calculus, the gradient of a scalar-valued differentiable function f of several variables is the vector field (or vector-valued function) ∇ f {\displaystyle \nabla f} whose value at a point p {\displaystyle p} is the vector whose components are the partial derivatives of f {\displaystyle f} at p {\displaystyle p} . That is, for f : R n → R {\displaystyle f\colon \mathbb {R} ^{n}\to \mathbb {R} } , its gradient ∇ f : R n → R n {\displaystyle \nabla f\colon \mathbb {R} ^{n}\to \mathbb {R} ^{n}} is defined at the point p = ( x 1 , … , x n ) {\displaystyle p=(x_{1},\ldots ,x_{n})} in n-dimensional space as the vector: ∇ f ( p ) = [ ∂ f ∂ x 1 ( p ) ⋮ ∂ f ∂ x n ( p ) ] .

Slope

In mathematics, the slope or gradient of a line is a number that describes both the direction and the steepness of the line. Slope is often denoted by the letter m; there is no clear answer to the question why the letter m is used for slope, but its earliest use in English appears in O'Brien (1844) who wrote the equation of a straight line as and it can also be found in Todhunter (1888) who wrote it as .Slope is calculated by finding the ratio of the to the between (any) two distinct points on a line.

‘y = mx + b’; ‘y = mx + c’; ‘vertical change’; ‘horizontal change’;
