Using differentials, find the approximate value of each of the following up to 3 places of decimal.
![]()
Consider y = ![]()
Let x = 32 and Δx = 0.15. Then, we get
Δy = ![]()
=![]()
![]()
⇒
= Δy + 2
Now, dy is approximately equal to Δy and is given by:
dy = ![]()

![]()
![]()
= 0.00187
Therefore, the approximate value of
is 2.00187.
