593. [U.] Note on the Equation of Time. (1) An elementary course on Astronomy forms part of the curriculum of many schools. I n this connection the Equation of Time forms such a good example on compounding two sine graphs that it seems worth while to suggest an elementary way of approaching it. The main difficulty in arriving a t the formula in an elementary way is due to the part of the Equation of Time that depends on the unequal motion in the Ecliptic. The part due to the obliquity of the…
