This book, based on Pólya's method of problem solving, aids students in their transition to higher-level mathematics. It begins by providing a great deal of guidance on how to approach definitions, examples, and theorems in mathematics and ends by providing projects for independent study. Students will follow Pólya's four step process: learn to understand the problem; devise a plan to solve the problem; carry out that plan; and look back and check what the results told them.

How do we find the courage to always be true to ourselves—even if we are unsure of who we are? That is the central question of international bestselling author Paulo Coelho's profound new work, The Witch of Portobello. It is the story of a mysterious woman named Athena, told by the many who knew her well—or hardly at all. Like The Alchemist, The Witch of Portobello is the kind of story that will transform the way readers think about love, passion, joy, and sacrifice.

Paulo Coelho: A Warrior's Life is the first-ever biography of the man whose books have sold an astounding 100 million copies worldwide, making him one of the bestselling authors of all time. Paulo Coelho's life begins with a complicated birth in Rio de Janeiro, Brazil, in August 1947. He was known as the "boy who was born dead" and who ultimately survived against all odds. Before he became internationally known as a worldwide bestselling author, Paulo lived many different lives. He flirted with suicide, was committed by his parents to insane asylums, suffered the brutality of electric shock therapy, dove into drugs, tried several varieties of sex, met the devil, spent time in prison, helped revolutionize Brazilian rock with musician Raul Seixas, and finally rediscovered his faith in 1986 as he walked the sacred Road to Santiago de Compostela, a medieval pilgrim's route between France and Spain. Coelho would later describe this life-changing spiritual experience in his first book, The Pilgrimage. The following year, The Alchemist established his worldwide reputation. The novel has already achieved the status of a universally admired modern classic. Now, for the first time, discover the life story of one of the most widely read and adored authors of our time.

With Anna-Marie McLemore's signature lush prose, Dark and Deepest Red pairs the forbidding magic of a fairy tale with a modern story of passion and betrayal. Summer, 1518. A strange sickness sweeps through Strasbourg: women dance in the streets, some until they fall down dead. As rumors of witchcraft spread, suspicion turns toward Lavinia and her family, and Lavinia may have to do the unimaginable to save herself and everyone she loves. Five centuries later, a pair of red shoes seal to Rosella Oliva’s feet, making her dance uncontrollably. They draw her toward a boy who knows the dancing fever’s history better than anyone: Emil, whose family was blamed for the fever five hundred years ago. But there’s more to what happened in 1518 than even Emil knows, and discovering the truth may decide whether Rosella survives the red shoes.
