This completely rewritten adaptation of Giesecke utilizes an abundance of hands-on activities and clear step-by-step descriptions to teach users freehand sketching and visualization skills for engineering graphics. The eighth edition features reorganized, consolidated coverage of Solid Modeling, new drawing problems, and fully proofed drawings. Other chapter topics include design and graphic communication, introduction to cad and solid modeling, freehand sketching and lettering techniques, geometric construction and modeling basics, multi-view sketching and projection, pictorial sketching, sectional views, dimensioning, and tolerancing, For individuals interested in the fields of technical drawing and engineering graphics.

This work develops the trigonometric functions using a unit circle approach and shows how it leads to the right triangle approach. Graphing techniques are emphasized, including a discussion of polar co-ordinates, parametric equations, and conics using polar co-ordinates.

OGT Exit Level Math prepares students for the Ohio Graduation Tests in mathematics at the high school level. This book is organized by Ohio state mathematics curriculum standards. Students learn what the standards say and what they need to know to pass the test. There is a pre and post test to measure progress. Examples of student work on open response questions help students see and correct mistakes.

This text focuses on understanding concepts rather than on presenting rote procedures, and blends the various topics and applications of contemporary precalculus. Graphical, algebraic and numeric perspectives are provided, offering a broad view of topics.
