Problems

1. p. 92 #4
2. p. 57 #6
3. As we did in class on Monday, March 21, find the following quantities for Deep Springs at sunrise on July 4: (a) note the Sun’s ecliptic longitude, (b) note the latitude of Deep Springs, (c) declination, (d) right ascension, (e) the ortive amplitude, (f) the ascensional difference, (g) the rising time — NB: July 4 is past the summer solstice, and this may affect your calculations (cf. Van Brummelen, p. 81) Also, solving your equation from p. 57 #6 part (a) for t and using your answers to the above, determine the amount of daylight at Deep Springs on July 4.
