what method do they teach you for finding the gradient at a point on a curved line? i only know calc so you need to say what other thing you're supposed to use. thnx
In my textbook it states: to calculate the gradient of a curve at a specific point, the following steps need to be taken:
*draw a tangent to the curve at the point
*calculate the gradient of the tangent
worked example : y = 2x^2, calculate the gradient of the curve at the point when x= 1
and then two graphs are given. a tangent is drawn at x =1
two points on the tangent are identified in order to calculate its gradient
gradient =10 - (-2) /3-0
gradient of function y = 2x^2 is 4.
and thats it then it gives us exercises to complete.
is there any way i can post images on this post? so i can show you the graph to the question im asking?
