Let Y = 1/x $\Delta$ X And $\Delta$ Y If X Changes from 1 to 1

Essay

Let y = 1/x.
a.Find $\Delta$ x and $\Delta$ y if x changes from 1 to 1.03.Round to six decimal places, if necessary.
b.Find the differential dy, and use it to approximate $\Delta$ y if x changes from 1 to 1.03.
c.Compute $\Delta$ y - dy, the error in approximating $\Delta$ y by dy.
