Introduction

Introduction: In this investigation I am going to investigate the gradient function of different lines. I am going find out the gradient of each line and then look at all the different gradients. With

Middle

is 9

I can see that each 3 gradients on each line are positive on the lines of y = x (3

y = x  (3             GR 18    GR 8   GR 1

y = 2x (3            GR 32   GR 28  GR 2

y = 3x (3            GR 40  GR 54  GR 3.25

Conclusion

GR 4

y = 2x (2           GR -14  GR -3  GR 13

y = 3x (2           GR -45  GR 33  GR  27.5

Formula: The formula is gr = a

Conclusion: I have found out that gradients increase when the line is made bigger. Also I have commented on different observations I have seen.

This student written piece of work is one of many that can be found in our GCSE Gradient Function section.

Calculus often deals with the following topics: 1. How to find the instantaneous change (called the "derivative") of various functions. (The process of doing so is called "differentiation".) 2. How to use derivatives to solve various kinds of problems. 3.

2. ## Curves and Gradients Investigation

h = 2x + h (cancel h) As the h value then tends to (gets closer to) 0, so the gradient function for the graph y = x² tends to 2x. This rule can then be applied to any point on the curve and will give the gradient at the point precisely.

Using this information I can conclude that the gradient on any point on that curve will be the cubed value of X. Therefore the gradient on this is m=3X 2 Using differentiation for Y=X3, I can write this gradient as dy dx Y=3X2 +5x My first fixed point is 3,

find the gradient of certain points on the graph x10 and then I will check to see if these are right using Omnigraph. If this gradient function, nx(n-1) is correct, then the gradient function of x10 will be 10x9. To prove that it is 10x9 I am going to draw up a table of values for certain x values.

I will now check the accuracy of these results using the increment method. Increment Method I will now perform the small increment method to check my gradients. I will perform the increment method for each of the curved graphs i.e.
