I have a 4 part problem that I am unsure what is being asked. I have shown what i have worked out.
a) Find the differential of y
b) Calculate dy when x=4 and delta x = 0.01. Interpret.
c) Calculate delta y when x =4 and delta x = 0.01. Interpret.
d) Illustrate dy and delta y. Interpret.
So what are they asking for "interpret" and "illustrate"?
