More Calculus: Find D'(x) for D = 50 / (0.01x^2 + 1)

[LegalManChris87]

The demand function for the Sicard wristwatch is given by:

D(x)= (50) / (0.01x^2 + 1)

where x is the quantity demanded in thousands and d(x) is the unit price in dollars.

a) Find D'(x)

b) Evaluate and interpret D'(5) and D'(10)

Once you complete part (a), then it's a simple matter of plug-n-chug for part (b). :wink:

D(x)= (50) / (0.01x^2 + 1)

a) Find D'(x)

How far have you gotten in applying the Quotient Rule (or Product Rule) to this? Where are you stuck?

Please be complete. Thank you!
