Almost every SAT math problem can be solved with
the below math. My DVD SAT math seminar shows how-to while covering the
Print (click icon below) the below ( if blank click here ), free, 6-page SAT Math Notes and use as a crash course and/or a quick reference "cheat sheet."
The 4-column, small-type, terse-wording design enables students to quickly find and read formulas. On a table or a large desk, 6-pages can be viewed instantly.
The two most commonly used polyamide grades by far are PA6 and PA66. The remaining members of the polyamide family are primarily used in applications that require unusually high service temperatures or tolerance of moist conditions. Bio-based and transparent (amorphous) PA grades are also available. In machine design purposes PA is often reinforced with glass or - in case of highly demanding applications - with carbon-fiber. Reinforcement changes the characteristics of the material and its applications considerably and therefore I’ll write a separate article on them later. This article focuses on unfilled PA6 and PA66.
