Examples are maximum one-day rainfalls and the time a user spends on a web page. ... infinite positive slope at x = 0 if 1 < k < 2 and null slope at x = 0 if k > 2.
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.
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 ...
If its second derivative is positive at all points then the function is strictly convex, but the converse does not hold. For example, the second derivative of f ( x ) = x 4 {\displaystyle f(x)=x^{4}} is f ″ ( x ) = 12 x 2 {\displaystyle f''(x)=12x^{2}} , which is zero for x = 0 , {\displaystyle x=0,} but x 4 {\displaystyle x^{4}} is strictly ...
Notice that the points (2,1) and (2,3) are on opposite sides of the line and (,) evaluates to positive or negative. A line splits a plane into halves and the half-plane that has a negative (,) can be called the negative half-plane, and the other half can be called the positive half-plane. This observation is very important in the remainder of ...
Examples of the application of the logistic S-curve to the response of crop yield (wheat) to both the soil salinity and depth to water table in the soil are shown in modeling crop response in agriculture. In artificial neural networks, sometimes non-smooth functions are used instead for efficiency; these are known as hard sigmoids.

For example, a slope that has a rise of 5 feet for every 1000 feet of run would have a slope ratio of 1 in 200. (The word "in" is normally used rather than the mathematical ratio notation of "1:200".) This is generally the method used to describe railway grades in Australia and the UK.
