"Calculus: The Musical!"—a comic review of the concepts and history of calculus—returns April 3 to North Central College as part of a national tour. Using musical parodies that span genres from light opera to hip-hop, the show is a blend of sketch comedy, musical theatre and classroom lecture. All this makes the learning of calculus fun and entertaining. Recommended for high school students and up, the show will take place at 7 p.m. Tuesday, April 3, in North Central College’s Pfeiffer Hall, 310 E. Benton Ave., Naperville. Admission is free. The performance is open to the public, and high school students interested in math are encouraged to attend.
