Using differentials, find the approximate value of each of the following up to 3 places of decimal.


Consider y =


Let x = 16 and Δx = -1. Then, we get


Δy =


=



= Δy + 2


Now, dy is approximately equal to Δy and is given by:


dy =





= -0.03125


Therefore, the approximate value of is -0.03125.
