CLUES:

1.         All students are located at integral coordinates in the xy-plane.  The x-coordinates belong to the set {-2, -1, 0, 1, 2}, and the y-coordinates belong to the set {-1, 0, 1, 2, 3}.

2.         Wallis is seated on the line which is normal to the curve f(x) = x2 – 2x + 4 at its minimum point.

3.         Newton is seated at a point of inflection of f(x) = 4x2 + .

4.         Euler sits at the point on the curve 2y = (x – 2)2 which is nearest to Boole.

5.         MacLaurin is located at the relative maximum point of the function f(x) = x3 – 3x2 – 9x – 4.

6.         Saccheri is seated at the absolute maximum point of the function f(x) = -x2 + 4x – 1.

7.         Riemann’s seat is one of the critical points of the curve f(x) =  - x3 + x2 – 1.

8.         The function f(x) = x2 +  has a point of inflection at x = 1.  Zeno sits at this point.

9.         Boole is seated at the absolute maximum point on the curve (x – 2)2 + y2 = 1.

10.       Archimedes is located at one of the vertices of the rectangle with the largest area that can be drawn with its upper vertices on the line y = 1 and its lower vertices on the parabola y = x2 – 2.

11.       Thales sits at a point on the curve f(x) = 2x3 – 6x2 + 43 where the slope is 48.

12.       Leibniz sits at a point on the curve y = cos(x) where the 99th derivative of that curve is 0.

13.       Kronecker sits on the line which is tangent to the curve y = 4x2 – 22x + 35 at the point (3, 5).

14.       Fermat is seated at the point of inflection of the curve y = x3 – 6x2 + 33x – 51.

15.       Descartes is located at one of the critical points of the curve y = -3x4 + 6x2.

16.       Cantor is located on the line tangent to the curve y = -x2 + 10x – 25 at its maximum point.

17.       Gauss sits at the absolute maximum point on the curve 4y = -2x3 + 3x2 + 7 over the interval

[-1, 2].

18.       Viete’s seat is collinear with those of Gauss and Kronecker.

19.       Heron is located at the point of inflection of the curve f(x) = x3 – 3x2 + 3x + 1.

20.       Pascal lies on the line tangent to the curve 12y = 16 – 6x2 – x3 at its point of inflection.
