1. a) Use a linear approximation to find an approximation for the cubic root of 1.2 and for the cubic root of 2. Hint

b) The exact values are: (cubic root of 1.2)=1.0626... and (cubic root of 2)=1.2599...

How do you explain the fact that the approximation you obtained at a) was better for the (cubic root of 1.2)

than for the (cubic root of 2)?
