Seen from the south an island has the shape like the graph of
y = f(x) = 2/(x^2 +1) – 1.
There’s treasure burried some place where the angle is 0.1 from the x-axis.
A) Show that there are such points on the graph.
B) Use Newton-Raphsons method or fixed-point notation to find a point where the treasure can be burried. The point should be given with an error of less than 0.0005 and marked with an “x”
