Scribage from 1/23/09
Today we started out by discussing test taking techniques:
-Always show exactly how you found an extreme (maxima or minima) by physically setting f’(x)=0
We also began work with slope fields. Slope fields help to determine what the family of curves will look like if the anti-derivative of a differential function is graphed. (f’(x)=2x is the differential equation of f(x)=x^2+c)
-The tangent lines represent the slope at the same point on the original function (the slope of the tangent line at a point is equal to the slope of the original function at that same point)
We also received a packet on slope fields that has problems for which we have to determine and graph the slope field.
