' Twenty-eight hundred students in the fall and 1 2,200 in the spring are the reasons instructors - , must convey such principles as L,Hospital's Rule ' and Cauchy's Sequences to several' math classes. f Compared to 1925 when math was a basic sub- 5 f ject taught in the evening after Main Avenue 1 High School classes were dismissed and when Plane ' Trigonometry, Analytic Geometry and Calculus ,,l...i . were the only courses, mathematics has increased V and grown into 88 fall and 91 spring day classes f under ten areas of math, including the latest, Ad- vanced Calculus. Mr. Joseph Edward Nelson, associate professor of math in the infant years of the department, was also director of the college. Now the department has 20 full-time and 20 part-time instructors. According to Mr. Elvis Sullivan, who came to SAC in 1958 and became chairman in 1964, De- grees and professional requirements have sent math on an upward climbf, Department chairman, Mr. Elvis Sullivan, inspects the trapezoid, cylinder, parallelogram and triangle blocks that adorn the fireplace of the Dewey Street Math Department office.

F1-Om six students to 102 over a period of three semesters indicates increasing interest in ASTRON- OMY, a science expanding along with space knowl- edge. Mr. Merwin Forbes started a night course in the spring of 1965. and in the fall. astronomy was of- fered in the day as well. This spring, student in- terest was so great that two day courses were formed. ln addition to star-gazing in the Planetarium, started in September l96l under the direction of Mr. Frank McConnell, students gathered on cam- pus on clear nights to view planets, galaxies, con- stellations, stars and asteroids through Mr. Forbes' telescope. Solar and lunar facts are a part of the course. Azimuth and altitude, 'latitude and longitude, the Vernal Equinox, and summer and winter sol- stices are used to indicate time and location. With the growing interest in Astronomy, a more advanced section will be offered next fall. L'Hospital's Rule is being proven by Rennie Harrison and Francisco Acosta in Mrs. Kathleen Burk's Calculus class. Mrs. Helen Wheeler explains how math n is applied to business to her Mathematics of Investment class.
