Thanks for responding.
First, where did you get the square root symbols and the textbook notation?
Secondly, I did try your method. I believe the idea is to, step one, use the power rule on the entire expression. Step two involves using the quotient rule to determine the derivative of the...
Find derivative of X/sqrt (x^2 + 1))
using the quotient rule and the power chain rule
x/(x^2 + 1) ^1/2
derivative of x=1
derivative of denominator=1/2(x^2 +1)^-1/2 times 2x
quotient rule:
[( x^2 + 1)^1/2 times 1] ( minus) x times [above derivative of denominator]
all of the above line...
Differentiate the following two problems.
1. x divided by the square root of x squared+ 1
2. The square root of x + 2
divided by the square root of x - 1
Thank you.
