Homework Statement
Hey guys!

So basically in the question I'm given the action

S=\int d^{d}x \left[ \frac{1}{2}\partial_{\mu}\phi\partial_{\nu}\phi\eta^{\mu\nu} - \frac{m^{2}}{2}\phi^{2}...

I'm slightly befuddled by is what it means when I'm asked to
Draw the Feynman diagram in momentum space for the two point function of $\frac{\lambda}{3!}\phi^3$ theory for order $O(\lambda^2)....

I want to insert a Feynman diagram into an equation, but when I do so, I find that the Feynman diagram and the rest of the equation are awkwardly aligned. The picture should make it pretty clear w...
