WebSlope, or m as we often write it in equations, describes the way a function changes. The slope of a function y (x) is the change in y divided by the change in x: (1) m = Δy/Δx. Linear graphs are graphs of straight lines, and can be defined by their slope, m, and their y-intercept, b: (2) y (x) = m*x + b. In the figure below, there is a linear ... In vector calculus, the gradient of a scalar-valued differentiable function of several variables is the vector field (or vector-valued function) whose value at a point is the "direction and rate of fastest increase". If the gradient of a function is non-zero at a point , the direction of the gradient is the direction in which the function increases most quickly from , and the magnitude of the gradient is the rate of increase in that direction, the greatest absolute directional derivative. Further, a point …

WebIn technical terms, the slope of the line is the change in y over the change in x. But I just like to think of it as rise over run. To find the slope of the line, pick two points on the line. Let's say we've looked at our graph, and have picked the points (3, 2) and (5, 6). Let's find how much the change in x aka the run is. To do that, we take ...

WebThe gradient is (normally) used when you have a scalar field, or function. A scalar field (or function) is when you associate a number to every point is space. The divergence is (again, normally) used when you have a vector field, or function. A vector field (or function) is when you associate a vector (let's say x,y and z) to every point in space.
