Evaluate using the Approximation and Error Method for
without using a calculator.
Solution:
Consider the given number
Let
If x = 1
then dx = 0.001
Substitute the values of x and dx to the above equation to solve for dy as follows
Therefore,
Check:
If you will use a scientific calculator,
which is almost the same as the final answer.
