RC097. Determination of the Direction of Qibla and the Islamic Timings
By M. Bashir Ahmad Bagvi
14 cm. x 21.5 cm.--- Page 86.

This booklet is intended to provide some guidance, rather inspiration, to the students of mathematics in general and those of engineering in particular. One might be able to construct (circular) monograms for the direction of Qiblah based on the determination of the azimuth. To make this work rather more useful and self-contained, methods of calculating the correct direction of Qiblah have been given. The longitude and latitude of any place are given in Section V to facilitate calculations where these cannot be obtained from any survey department. Similarly, these days when air service has become quite common, it is of use to man to know the time at which the sun would set so that he may offer his Maghrib prayers or break his fast while in the air. Section VI deals with this particular aspect of the problem.
