Using differentials, find the approximate value of each of the following up to 3 places of decimal.
![]()
Consider y = ![]()
Let x = 0.0036 and Δx = 0.0001. Then, we get
Δy = ![]()
=![]()
![]()
⇒ 
 = Δy + 0.06
Now, dy is approximately equal to Δy and is given by:
dy = ![]()
![]()
![]()
= 0.00083
Therefore, the approximate value of 
is 0.06083.
