According to years of expertise instructing and writing supplemental fabrics for extra conventional precalculus texts, Reva Narasimhan takes a functions-focused method of instructing and studying algebra and trigonometry techniques. This new sequence builds up appropriate innovations utilizing features as a unifying subject, repeating and increasing on connections to uncomplicated capabilities.

The current booklet relies at the lecture given by means of the writer to senior students in Moscow at the twentieth of April of 1966. the excellence among the fabric of the lecture and that of the booklet is that the latter comprises workouts on the finish of every part (the such a lot tricky difficulties within the workouts are marked by means of an asterisk).
