Triangle Geometry Practice
- Dr. Doug Davis, 3D
This book contains several interactive pages for helping to learn trigonometry. They progress in difficulty from trigonometric definitions to solving for triangle values. It progresses from identifying the sides of a right triangle, through the definitions of trigonometric functions to solving values of oblique triangles. Actual numbers are never solved but the selection of the approach to use is practiced. To often I see people stare at a problem and say I do not know where to begin. These applets are intended to help in learning where to begin in solving trigonometric problems.
