Value of second derivative at a given point?

Click For Summary
SUMMARY

The discussion centers on evaluating the second derivative of a function at the point (1,1) using the formula d2y/dx2 = (4(dy/dx) - 12x^2 - 12y^2(dy/dx)^2) / (4y^3 - 2x). The correct value of the second derivative at this point is -14. Participants clarified that the value of dy/dx is -1, which is crucial for substituting into the equation to arrive at the correct answer.

I'm not sure how to evaluate the second derivative

d2y/dx2 = (4(dy/dx) -12x^2 -12y^2(dy/dx)^2)) /(4y^3 - 2x)
AT A GIVEN POINT (1,1). The answer is -14 not sure how they got it.

Final exam this friday would appreciat e answers very much!

hi ashina14! :smile:

(try using the X2 button just above the Reply box :wink:)

what is the complete question? :confused:
 
Didn't occur to me that the value of dy/dx would play a role. But it is -1 and now I know I just need to substitute it in this equation wherever appropriate! Stupid question! :P
