Single-Variable Calculus
Alejandro José Soto Franco
A course in the calculus of one real variable, written for a reader who has met algebra and trigonometry in school and is ready to see why the methods of calculus work. Every result is proved in the text or in an appendix. The book is organised around the differential operator: dx is the differential of the coordinate function, and integrals integrate 1-forms. From the third chapter, the book states limits, continuity, the derivative and convergence in normed spaces. The sup norm on a space of functions stands beside the absolute value on the line. Every section ends with problems graded by difficulty, each with a hint, an answer and a full solution, and every answer is checked by computer algebra.

Alejandro José Soto Franco
Model United Nations has no central authority, no single rulebook, and no body that certifies what a delegate has learned. This book describes the activity as it is actually practised: what it is and where it came from, how a committee works from the roll call to the vote, and how a delegate prepares, speaks, negotiates, and drafts. It is written for new delegates, veterans, team leaders, coaches, parents, and school administrators, and each of them can read the chapters written for them without reading the rest.
