About The Book
Good knowledge of basic mathematics is essential for the students and professionals in science, technology, engineering, and mathematics (STEM) to excel while working on a problem or project. A concise but complete handbook of a targeted subject, accessible in any manner, can help when such knowledge is in need. Here topics and formulas in trigonometry, including all the key elements, are selected carefully and presented most efficiently.This book can be used by all the STEMers as a review on trigonometry to prepare for a class or project in science or engineering, or as an essential reference to check on or look up an issue in trigonometry during a working session. Sufficient explanation is given wherever clarification is needed.
