Write all spherical harmonics up to l = 2 (there are nine of them) in Cartesian form, i.e. give expressions in terms of x, y, z, and r. You can either use the Rodrigues formula for the Legendre polynomials or start with the given expressions for Y m l in terms of θ and φ. In any event you must show your work.

Bordered Hessian element The Lagrangian is L=ln(x+y^2) -z^3/(3*y) -x*y +λ*(x*z +3*x^2*y -r), where r is a parameter (a known real number). Here, ln denotes the natural logarithm, ^ power, * multiplication, / division, + addition, - subtraction. The border is at the top and left of the Hessian. The variables are ordered λ,x,y,z. Find the last element in the second row of the bordered Hessian at the point (λ,x,y,z) =(0.11, 0, 2440, 0.01167). This point need not be stationary and...
