Hi,

From http://localhost:8888/kernelspecs/sagemath/doc/prep/Calculus.html:

%auto
f(x)=x^3+1
@interact
def _(c=(1/3,(-1,1))):
    P=plot(f,(x,-1,1))
    fprime=derivative(f,x)
    L(x)=fprime(c)*(x-c)+f(c)
    Q=plot(L,(x,-1,1),color="red", linestyle="--")
    show(P+Q+point((c,f(c)), pointsize=40, color='red'),ymin=0,ymax=2)

There was an error:

UsageError: Line magic function `%auto` not found.

`lsmagic` gives this:

Please help me to understand the function of '%auto' (is there a reference 
for sage 'magics' ?). Is '%auto' a line magic or cell magic or something 
else?

Thank you for your help.

Regards,

phiho
