I have a problem that states: Find the derivative of y with respect to x
y = ln (1/x(sqroot x + 1)
The answer in the back of the book has (3x + 2) / 2x(x+1) as the answer and I don't understand how they came to this.
Exactly where is your difficulty?
. . Log rules?
. . The derivative of logs?
. . You really suck at algebra?
Simplify first . . .Differentiate: .
The answer in the back of the book has:
. . This should have a "minus" in front.
