Spherical Trigonometry 16 by gothic5 Can anyone recommend a book on spherical trigonometry? I bought one (Schaum outline series) where it gives a lot of formulas for calculating triangles applied to circles but it dosen't really give specific values.Plugging in values to ABC abc makes the text clear to me.Also curious if anyone has read Glen Van Brummelen/Heavenly Mathematics: The Forgotten Art of Spherical Trigonometry which talks about celestial calculations of ancient Egypt and Greece.Request any info-Thank You Harold Quote Tue Jan 03, 2017 12:33 pm
