rho = function('rho',u)
u_z_equation = u*z^3 - u*z^2 - z^3 + z^2 - 2*z + 1
implicit = u_z_equation(z=rho)
rho_1 = solve(implicit(u=1),rho(1))[0]
print rho_1
d_rho = solve(diff(implicit,u),diff(rho))[0]
print d_rho(u=1)
But I do not know how to substitute the value I found for rho(1) into the expression for the derivativebrettpimFri, 05 Apr 2019 22:28:44 +0200https://ask.sagemath.org/question/46026/Evaluation failhttps://ask.sagemath.org/question/26374/evaluation-fail/hello,
when running "0^0" the result is "1", but when defining "f(x)=0^x" and evaluating "f(0)" the evaluation fails with "ValueError: power::eval(): pow(0,0) is undefined". I guess this one is easy to fix... :)

How can I get the value of a 2D function, say f(x,y)=x^3+y^3, along the path determined by a parametric function, say M(x(t)=cos(t),y(t)=sint(t))?
