Calculus is used by taking the derivative of the log-likelihood function with respect to the parameter, setting it to zero to find critical points, and using the second derivative test to confirm that the critical point is a maximum.

Conditions: The log-likelihood function is differentiable with respect to the parameter $\theta$.; The parameter space allows for a maximum to exist.
