Gradients and the rate of change
WebThe gradient is a fancy word for derivative, or the rate of change of a function. It’s a vector (a direction to move) that Points in the direction of greatest increase of a function ( intuition on why) Is zero at a local … 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).. This will correspond to the gradient of the curve at that individual …

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 …
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. P and Q are chosen as two points at either end of the line shown. Their coordinates are … See more Obtaining the wrong sign on the value of a gradient is a common mistake made by students. There are two ways of dealing with this. One is to recognise that the graph slopes the … See more As is often the case, there are new levels of complexity once we start looking at real chemical examples.
