Quiero realizar un calculo simbolico pero no me funciona, al colocar syms x me sale error
Como puedo verificar que tengo habilitado el calculo simbolico
[Google Translate]: I want to perform a symbolic calculation but it doesn't work, when placing "syms x", I get an error. How can I verify that I have symbolic calculation enabled?

You need to install the Symbolic Toolbox
If you are lucky, then possibly you already have a license for it. Use the Add-On Explorer and search for Symbolic Toolbox. If you already have a license for it then there will be a button to install the toolbox.

Is this what you are trying to achieve (È questo ciò che stai cercando di ottenere?):
% Initialize symbolics
syms H(x) F(x,y) G(x, y, z)
% Initialize symbolic functions
H(x) = sin(x)
H(x) =
F(x, y) = x^2+y^2+2*x*y
F(x, y) =
G(x, y, z) = sqrt(x^2+y^2+z^2-25)
G(x, y, z) =
% Calculations:
H(pi)

0
F(1, 2)

G(1, 2, 3)
