Calculus 1 Quiz Questions and Instructions from Prof. Brick, Exercises of Calculus

Instructions and questions from a series of calculus quizzes given by prof. Brick during the fall ’00 semester. The quizzes cover various topics in calculus, including limits, derivatives, and integrals. Students are asked to print their names, discuss their reasons for taking the course, and estimate slopes of tangent lines. Some questions require the use of calculus concepts to find formulas, limits, and tangent lines.
