The maximum angle $\phi$ that the pendulum's string makes with the vertical corresponds to the amplitude $A$ in the solution $\phi=A \cos (\omega t+\theta)$. The amplitude $A$ represents the maximum displacement from the equilibrium position, which in the context of a pendulum, is the maximum angular displacement from the vertical.

For a Swinging Pendulum, the Maximum Angle That the Pendulum's ϕ=Acos⁡(ωt+θ)\phi=A \cos (\omega t+\theta)ϕ=Acos(ωt+θ)
