Ah yes, because who wouldn't want to dive into a delightful cocktail of Mollweide maps and Newton's method? 🌍🔧 It's like the author thought, "Let's combine the most thrilling topics in math to really captivate the masses!" 🎉 Too bad they forgot the part where anyone actually cares. 🙄

Mollweide map projection and Newton’s method

The Mollweide equal-area projection map requires solving a nonlinear equation. Newton's method solves this equation well except at high latitudes.

Math Question:

What are the conditions for Newton's method to converge?
Specifically: How fine a net of initial values would I need to cast to find all real zeros(in t) of

`` cos(ct) - cos(d)•cos(t0-t)`` ?

c, d and t0 are real numbers.

truncated sample mean using middle 24% order statistics is~ 88% as asymptotically efficient an estimator of { x_{0}} as ml estimate.w #Newtonsmethod it be used as an initial solution for {x_{0}}
