when , or
note: any info given on the range of values for r ?
... a decrease in r at 1/8 of a percent
there is your 1% increase in r
I am unable to get the right answer, closest answer : -0.01(r-1)
Trying again and again it keeps raising a lot more of other questions, that is simply boring for me.
Would be more than grateful if someone could kindly show me a detailed steps to the solution please.
(JF Talbert Textbook, Exercise 16D, Q.22)
For the function A=1/(r-1)^2 , a small change in r when r=2(r-1)^2 produces a 2% reduction in the value of A.
Find the approximate change in r.
(Given Answer: 0.01 increase)
I have reviewed the problem, it comprises of 3 stages:
I. Solving for from , gives
II. Solving for from , gives:
III. And finally, Solving for from , that is a) or b)
Sir, hope you take into consideration stage II. that lead to a different solution.
