The gradient is a fancy word for derivative, or the rate of change of a function. Itâs a vector (a direction to move) that. 1  Points in the direction of greatest increase of a function (intuition on why)  Is zero at a local maximum or local minimum (because there is no single direction of increase)
The gradient of a line or the slope of a line is an indication of how steep a line is at a particular point. The gradient is particularly important in Physics and as a result it is particularly important that you understand how to calculate it perfectly.ou can choose any coordinate on the tangent. Hence using the coordinated below the gradient of the curve at the point (3,27) is. Gradient of curve at point (3,27) = (60 â 4)/(4 - 2.5)= 56/1.5 = 37.3 =37 (2 sf). As you can see it is easy to calculate the gradient of a straight line or a curve at a particular point.
