The mathematics textbooks for grades 11 and 12 of the specialized secondary school are tailored to the non-technical fields of economics and administration, health and social services, design, nutrition, and agricultural sciences in Lower Saxony. Each topic is developed around a job-related practical situation. Illustrative, subject-specific problem scenarios promote fundamental subject and methodological competence. Volume 2 for grade 12 offers numerous learning situations with fully worked-out solutions for each topic, achieving a high degree of clarity and comprehensibility. Numerous exercises at the end of the chapters cover the mandatory learning areas of polynomial functions, differential calculus, and integral calculus, as well as the optional learning areas of exponential functions, rational functions, linear algebra, and statistics. The new edition has been extensively revised.
