20. The difference of arc between the suns right ascension andUs longitude gives rise to one part of the equation of time. What isthe suns right ascension when this part of the equation is a maxi-mum, and what is the maximum value? *Ans. Suns Long. 46° 14 10R. A. 43° 4560 Difi*. 2° 28 20=9m 54.6 *.… … MAXIMA AND MINIMA. 211 22. Within a triangle is a given point P, the distance to the near-est angle A is given, and the line AP divides the angle A into twoangles m and n, of which m is greater than n. It is required to find the line EF dra-ivn through the point P, sothat the triangle AEF shall be…
