Calculus

Power Rule, Constant Multiple Rule, Derivative of Sin and Cos.

Discuss d/dx notations versus f ' (x) notation

Derivitaves are more than yet another operation, like raising to a power or taking a square root, they produce slope functions and functions that have meaning on their own...  such as the first derivative of the gravity acceleration function being a velocity function... and the derivative of the velocity function being the position function.

Aside:  Why Gravity is not a force:




Gravity and velocity of stellar objects  could prove to be life-changing for us humans walking around on Earth.



Dont' think it could happen...?  Small impacts happen all the time...  with dramatic effect.

Discuss the general shape of the objects, that the Midsegment is parallel to the base(s) and Corresponding angles, etc create proportional (similar) objects nested one inside the other.

Work thru example 2 p. 185.  Decide what the width of the top "base" of a Triangle is...  and how this relates to the "averaging of the midsegment and the top and bottom base of a Trapezoid.

Work a few more problems from board them turn them loose with p. 186/187 (8; 10-18)
