Chapter One. Lines and conic sections -- Chapter Two. New coordinate system -- Chapter Three. Sequences and series -- Chapter Four. Special topics -- Chapter Five. Trigonometric functions -- Chapter Six. Analytic trigonometry.

This concept-based and learner-centered mathematics book is intended for grade 11 senior high school students. This book aims to help students become independent thinkers and lifelong learners.
The three main goals of this book are (1) to align the Common Core Standards of K to 12 Curriculum to Mathematics Learning Competencies of the Department of Education, (2) to more effectively leverage the use of technology in the mathematics class, and (3) to instill to students a deep understanding of, and appreciation for mathematics in general.
This book covers Analytic Geometry, Sequences and Series, Mathematical Induction, and Trigonometry (Circular Functions, Trigonometric Identities, Inverse Trigonometric Functions, and Polar Coordinate System). With this book, the learner is expected to achieve mastery of core competencies needed as prerequisites to Basic Calculus and other disciplines in Mathematics in general.
It is our hope that this book provides the Senior High School students under the STEM starnd with understanding of the essentials of Precalculus.
