9.9 Small Changes and Approximations
This is very useful information in determining an approximation of the change in one variable given the small change in the second variable.
Given that y = 3x2 + 2x – 4. Use differentiation to find the small change in y when x increases from 2 to 2.02.
The small change in yis denoted by δy while the small change in the second quantity that can be seen in the question is the x and is denoted by δx.
