WebThe concepts of gradient and rate of change are explored. If the distance and time of a moving car is plotted on a graph, this can be used to calculate the speed. The speed is … The gradient can be defined using the generic straight line graph (fig 1). To determine the gradient of the straight line we need to choose two points on the line, here labelled as P and Q. The gradient mof the line between these points is then defined as: The reason for using the term ‘increase’ for each … See more The images that teachers and students hold of rate have been investigated.2This study investigated the relationship between ratio and rate, and identified four levels of imagery with increasing levels of sophistication: 1. … See more A very simple example (fig 2) will illustrate the technique.

WebA Directional Derivative is a value which represents a rate of change; A Gradient is an angle/vector which points to the direction of the steepest ascent of a curve. Let us take a look at the plot of the following function: … WebOct 9, 2014 · The gradient function is used to determine the rate of change of a function. By finding the average rate of change of a function on the interval [a,b] and taking the limit as b approaches a, the instantaneous rate of change can be found, which tells you how quickly the function is increasing or decreasing at a.

WebEstimating Rate at a Given Point. We calculate the instantaneous rate of change by drawing a tangent to the curve (a straight line just touching the curve) at the desired point, and then calculating the gradient of this tangent (which can be worked out using standard straight line methods)..
