Students will naturally ask, "When will I use this stuff?" With some mathematical concepts, the answer will be a definite "Never!" However, it is very likely you will require trigonometry in some form. You may only need some of the trigonometry topics, but applications similar to the ones contained in this book will probably be required.One of my students worked with a construction firm. He was required to determine whether or not the dump trucks would be in any danger of hitting the overhead hydro wires, preferably with an accurate solution.This book is designed to teach the skills required to be successful solving problems involving triangles.It is suitable for an independent learner, a student in a class, parent, tutor, or for a teacher.
