WOMEN OF SCIENCE HIGHLIGHTS OF S. XX
The American Fanya Montalvo, was once the only girl enrolled in the career of Physics at
Chicago. His specialty, Mathematical Psychology, which allowed him to study human behavior

Quadratic and Cubic Equations. A different approach.
Let's start with our old friend, the quadratic equation:
y = x2 + bx + c = 0.
We know that relations between coefficients and roots, is given by:
x1 + x2 = -b; x1.x2 = c; then we can postulate that
x1 =
STATUS OF XVII CENTURY
The calculus was created to solve major scientific problems of the seventeenth century, for
example, to obtain lengths of curves, areas and volumes of geometric bodies, tangent to a
curve and maxima and minima of functions.

FUNCTION
A function is a correspondence between joint that occurs when each of the elements of the first
set is connected with one element of the second set. We are in the presence of a function when
each element of the first set only get a single arrow.
How we choose the items?
The choice of items is made by the author of the test, taking into account:
To be representative of the attribute that I want to measure, how it manifests that attribute?
direct observation, define what the demonstration, taking f
