Question

Use a linear approximation (or differentials) to estimate the given number. (use the linearization of 1/x. do not round your answer.) 1 /1001

Answer 1

Thank you for posting you question here at brainly. Below is the solution:

1/97 = 1 / (100-3) = 1 / (xo + dx) 

so, you have now that 

x = xo + dx, where x = 97, xo = 100, and dx = - 3. Recognizing that 3 << 100, we can write the Taylor expansion around xo 

1/ (xo + dx) ~ 1/xo + d/dx(1/xo)dx = 1/xo + (-1/xo^2)dx 

= 1/100 - (1/100^2) (-3) = 1/100 + 3/100^2 
= 1/100 + 3/10000 
= 0.01 + 0.0003 
= 0.0103
