Passing Notes

This is a four page packet which covers basic trigonometry, particularly that needed for precalculus classes. The reviews and diagrams introduce the concept of radians, and the unit circle, not only explaining how to use them, but why we use them to impart a thorough understanding to students. The packet includes definitions of trig. functions, basic graphs of all six functions (along with domain and range) trigonometric identities, double angle formulas, half angle formulas, product to sum equa

This is a three page packet which is perfect for teaching,and reviewing logarithms. It covers the definition of a logarithm and natural logarithm, change of base formula, and the characteristics of logs. This packet not only shows how to expand and collapse logs, but it why we can manipulate them the way we do. Logarithms are often a tough subject when first introduced, since they are intertwined with the characteristics of exponents. This packet thoroughly explains the mechanisms behind logs, t

This is a one page reference material which lists the three basic identities, double angle formulas, half angle formulas,addition & subtraction expansions, product to sum, and sum to product identities.
