Hi, I am trying to graph(adsbygoogle = window.adsbygoogle || []).push({});

(x+(1/√(1+cos(x)²)))

in mathematica, and i used

Plot[x + (1/(sqrt (1 + cos (x)^2))), {x, 0, 9}]

but I am not getting an output graph.

Any ideas?!

Plot[x + 1/Sqrt[1 + Cos x^2], {x, 0, 9}, PlotRange -> {-10, 10}]

I found few errors, and above is what I got, it's a progress, but now I get this error:

Plot::exclul: {Im[Cos x^2]-0} must be a list of equalities or \

real-valued functions.
