Slope may still be expressed when the horizontal run is not known: the rise can be divided by the hypotenuse (the slope length). This is not the usual way to specify slope; this nonstandard expression follows the sine function rather than the tangent function, so it calls a 45 degree slope a 71 percent grade instead of a 100 percent. But in ...
This is a collection of temperature conversion formulas and comparisons among eight different temperature scales, several of which have long been obsolete.. Temperatures on scales that either do not share a numeric zero or are nonlinearly related cannot correctly be mathematically equated (related using the symbol =), and thus temperatures on different scales are more correctly described as ...
The WI-grade is for "hard ice"; steep snow slopes, which are encountered frequently on alpine climbing routes, are not explicitly graded but instead, their steepest angle (approximate figure or a range) is quoted (e.g. 60–70 degree slope). [27] [28] WI-grade is for "seasonal" hard ice; an AI prefix is used instead for "alpine ice", which is ...
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.
When distances are measured along the slope, the equivalent horizontal distance may be ... C equal to 0.000,011,6 units per unit length per degree Celsius ...
Stream gradient (or stream slope) is the grade (or slope) of a stream. It is measured by the ratio of drop in elevation and horizontal distance. [ 1 ] It is a dimensionless quantity , usually expressed in units of meters per kilometer (m/km) or feet per mile (ft/mi); it may also be expressed in percent (%).
In trigonometry, the gradian – also known as the gon (from Ancient Greek γωνία (gōnía) 'angle'), grad, or grade [1] – is a unit of measurement of an angle, defined as one-hundredth of the right angle; in other words, 100 gradians is equal to 90 degrees.
Incline from the Causeway Street Tunnel up to the Lechmere Viaduct on the Green Line (MBTA), Boston, Massachusetts, United States [15] This incline is commonly believed to be the "steepest grade of tracks in the T system."
