Limit of a Function Hardest Math Concept in Student Learning The fact that we live in a world of numbers was clearly illustrated by the enrollment in math. Of the 1116 students at Encinal, 772 of these were ina math class. One nice thing about the math depart- ment was that all full time mathematicians taught some form of advanced math; either algebra or geometry. Our students filled the classes to capacity. Out of curiosity the Horizon asked our resident mathematicians what exactly was the easiest and the hardest concept for students to grasp. The answer was suprising. Trig functions were easiest for students to pick up and understand although, Ed Boughton, speaking for the math department, said no one knew why they were so easy for most studnets. On the other hand the hardest concept w was found in math analysis; it was the limit of a oe function. All math students were attempting to master math because they knew their futures depended on a solid math background. RIGHT: BRIDGET MOSELY gives a big smile as she gets a problem on her test.
