question for a beginner

hey, when using syms y(x) do I define both y and x as symbolic? I thought that I have to write it this way - syms y(x) x

Not necessarily.

This works:

syms y(x)  
y(x) = x^2;

as will this:

syms y x 
y(x) = x^2;

while this will throw an error:

syms y   
y(x) = x^2;

I default to defining all variables in a syms declaration, just to be safe (and compulsive).
