WebNow, sin(y)=0 when y=nˇ, for all integers n. Then setting 1 +xcos(nˇ) =1 +(−1)nx=0, we get that critical points are: (x;y)=((−1)n+1;nˇ) for n∈Z: At these points: f xx≡0; f xy=cos(nˇ)=(−1)n; f yx=cos(nˇ)=(−1)n; f yy=−xsin(y)S((−1)n+1;nˇ) =−(−1)n+1 sin(nˇ)=0: So the Hessian matrix at ((−1)n+1;nˇ) is: 0 (−1)n (−1)n 0 with determinant D=−(−1)2n =−1 … Weband the first derivative as a function of xand yis (Equation 1) To find y'' , differentiate both sides of this equation, getting Use Equation 1 to substitute for y' , getting (Get a common denominator in the numerator and simplify the expression.) This answer can be simplified even further. x2+ xy+ y2= 1 , so that (Equation 2) x2+ y2= 1 - xy.

WebImplicit differentiation is a way of differentiating when you have a function in terms of both x and y. For example: x^2+y^2=16. This is the formula for a circle with a centre at (0,0) and a radius of 4. So using normal differentiation rules x^2 and 16 are differentiable if we are differentiating with respect to x.
