Slope illustrated for y = (3/2)x − 1.Click on to enlarge Slope of a line in coordinates system, from f(x) = −12x + 2 to f(x) = 12x + 2. The slope of a line in the plane containing the x and y axes is generally represented by the letter m, [5] and is defined as the change in the y coordinate divided by the corresponding change in the x coordinate, between two distinct points on the line.
l = slope length α = angle of inclination. The grade (US) or gradient (UK) (also called stepth, slope, incline, mainfall, pitch or rise) of a physical feature, landform or constructed line is either the elevation angle of that surface to the horizontal or its tangent. It is a special case of the slope, where zero indicates horizontality. A ...
Numbers whose exponent is too large to represent instead "overflow" to positive or negative infinity (+∞ or −∞), while numbers whose exponent is too small to represent instead "underflow" to positive or negative zero (+0 or −0). A NaN (not a number) value represents undefined results.
A drawing of the Petersen graph with slope number 3. In graph drawing and geometric graph theory, the slope number of a graph is the minimum possible number of distinct slopes of edges in a drawing of the graph in which vertices are represented as points in the Euclidean plane and edges are represented as line segments that do not pass through any non-incident vertex.
If the slope is positive, >, then the function () is increasing; if <, then () is decreasing In calculus , the derivative of a general function measures its rate of change. A linear function f ( x ) = a x + b {\displaystyle f(x)=ax+b} has a constant rate of change equal to its slope a , so its derivative is the constant function f ′ ( x ) = a ...
Signed zero is zero with an associated sign.In ordinary arithmetic, the number 0 does not have a sign, so that −0, +0 and 0 are equivalent. However, in computing, some number representations allow for the existence of two zeros, often denoted by −0 (negative zero) and +0 (positive zero), regarded as equal by the numerical comparison operations but with possible different behaviors in ...
This operation is undefined in arithmetic, and therefore deductions based on division by zero can be contradictory. If we assume that a non-zero answer n {\displaystyle n} exists, when some number k ∣ k ≠ 0 {\displaystyle k\mid k\neq 0} is divided by zero, then that would imply that k = n × 0 {\displaystyle k=n\times 0} .
The points of this projective plane are the equivalence classes of the set K 3 \ {(0, 0, 0)} modulo the equivalence relation. x ~ kx, for all k in K ×. Lines in the projective plane are defined exactly as above. The coordinates (x 0, x 1, x 2) of a point in PG(2, K) are called homogeneous coordinates.
