An updated solucionario is a powerful tutor – but only if used correctly. Follow this protocol:
First published in the early 20th century, Granville’s approach to trigonometry was revolutionary in its clarity. Unlike modern textbooks that sometimes prioritize visual gimmicks over rigor, Granville’s work is lean, precise, and logical.
Un solucionario actualizado no es un "atajo" para copiar respuestas; bien usado, es un tutor asíncrono. El estudiante idealmente:
Para el profesor, representa una herramienta para generar variantes de problemas (cambiando un ángulo o lado) con confianza en la solución. An updated solucionario is a powerful tutor –
The first half of the book covers:

Yes, with a few caveats.
If you are using Granville’s Trigonometría Plana y Esférica as your primary textbook, this updated solucionario is practically indispensable. It transforms the classic text from a challenging puzzle into a teachable, learnable system. The clarity of the solutions, the correction of old errors, and the addition of extra problems make it a significant improvement over any previous version.
However, if you already feel confident in both plane and spherical trigonometry and only need final answers for checking, the manual may feel overly detailed. Also, if you prefer interactive digital learning, you might want to supplement this with 3D geometry software or online spherical trig simulators.
