Can someone please give me the full detailed solutions for both problems? The questions are to find the derivative functions of these functions (using the quotient rule).
Problem 1:
y = (r^2)/(1 + sqrt(r))
Problem 2:
f(x) = x/(c + c/x)
Answer (1): y' = r(4 + 3sqrt(r))/2(1 + sqrt(r))^2
Answer (2): y' = 2cx/(x^2 + c)^2
Any help would be greatly appreciated!
Thanks in advance!
Then how about you show all your workoing so that we can see what is your problem. Or just use this website: http://www.wolframalpha.com/.
Tsk tsk skeeter. Your pay will be docked this week. (Sheesh, that's the thanks you get ....).
