Matematika pro dvouleté a tříleté obory SOU 2.díl – Calda Emil (2010)

The second part of the textbook, like the first part, is intended for both two-year and three-year programs, but thanks to the clear graphical markings, it is evident which sections are common and which are only for the three-year programs. This second part continues the overall concept and method of explanation from the previous part. It further expands and deepens knowledge from elementary school, emphasizes the practical application of acquired knowledge, and pays appropriate attention to working with a calculator. The introductory chapter reviews the material on linear equations and their use in solving word problems. The second chapter transitions to quadratic equations, equations with unknowns in the denominator, and relevant word problems. Chapter three contains material on systems of equations with two and three unknowns and systems of inequalities with one unknown. In chapter four, after introductory articles on the general concept of functions and their graphs, linear functions, quadratic functions, inverse proportionality, and trigonometric functions in the range of 0° to 360° are discussed in detail. Graphs of functions are used for graphically solving a system of two equations and also a quadratic equation. The content of the final chapter is stereometry. The first two articles discuss the mutual positions of lines and planes and their...
