Exploring maximum likelihood using graphs in TI Nspire

Consider a case of binomial process with n=10, exploring the likelihood function in TI Nspire using variable slider p:

For the log function, window settings has to be adjusted for a complete picture.

Besides graphical solutions, the maximum can also be obtained from differentiating with respect to p for a zero result:

For usage in logistic regression, the Nelder-Mead method can be applied for determining the maximum value.
