,
therefore ...
see the difference between and ?
With the information given compare delta y and dy.
1. y=(x)^3 x=1 delta x= 0.1
dy= f'(x)(dx)
dy= 3(1)(0.1)
dy=.3
delta y= f(x+delta x)- f(x) I am having trouble finding delta y
delta y= (1+.1)-(1) ? Is this what I would do
My second question is similar
2.y= x^4+1 x=-1 and delta x=.01
dy=(-4)(-1)(.01)
dy=.04
But I am having trouble finding delta y
