SUMMARY
The discussion centers on finding the tangent plane to the surface defined by the equation F(x,y,z) = (y^3)(z^3) - x = 0. The user calculates the gradient of F, resulting in Gradient F = -1i + 3y^2(z^3)j + 3z^2(y^3)k, and evaluates it at the point (1,-1,-1), yielding the tangent plane equation x + 3y + 3z = -5. Despite the calculations, the user expresses confusion over the correctness of their answer, suggesting a potential misalignment with the expected solution from Wiley Plus. The user plans to consult their professor for clarification.
