A typical solved problem: "Given two points on Earth with latitudes and longitudes, find the shortest distance between them along the surface." The solucionario will walk you through converting to radians, applying the spherical law of cosines, and then converting the angular distance to kilometers.
If you want, I can now produce (e.g., a working HTML/JS tool) for one of these features, such as the plane triangle solver or log table simulator . Just tell me which. Trigonometria plana y esferica de granville solucionario
