Precalculus: Mathematics for Calculus is a comprehensive textbook that builds a solid foundation in algebra and trigonometry while progressively preparing students for the rigors of calculus. It begins by establishing fundamental algebraic concepts such as the real number system and operations, then advances through detailed explorations of functions, polynomial and rational expressions, and exponential, logarithmic, and trigonometric functions using both unit circle and right triangle approaches. The text further delves into advanced topics including analytic trigonometry, polar and parametric equations, vectors, systems of equations, and conic sections, seamlessly integrating theory with real-world applications. With its final chapters on sequences, series, and an introduction to limits, the book effectively bridges the gap between basic mathematical principles and the foundational concepts required for calculus.

Problem 5
Electric fans $A$ and $B$ have radius 1 ft and, when switched on, rotate counterclockwise at the rate of 100 revolutions per minute. Starting with the position shown in the figure, the fans are simultaneously switched on. (a) For each fan, find an equation that gives the height of the red dot (above the horizontal line shown) $t$ minutes after the fans are switched on. (b) Are the fans rotating in phase? Through what angle should fan A be rotated counterclockwise in order that the two fans rotate in phase?
