Title: How can I find the derivative of this function via definition of a derivative? Post by: tony1653 on Feb 27, 2013 I'm suppose to find the slope of the tangent to the curve at the point where x=a.
The equation is Y= 9/(sq. root of x). I'm not allowed to use the quotient rule. Please help, I have tried but to no success. Title: How can I find the derivative of this function via definition of a derivative? Post by: Tony2001 on Feb 27, 2013 No need to use the quotient rule..
9/Sqrt(x) is equivalent to 9(x)^(-1/2) at which point the derivative is -9/2(x)^(-3/2). Title: How can I find the derivative of this function via definition of a derivative? Post by: rivers.butterfly on Feb 27, 2013 Content hidden
