This task launches with a story retold by Ben Orlin about the famous detective Sherlock Holmes.

youcubed: Curved Shapes
youcubed (Stanford University)

This activity is an occasion for creative and intuitive thinking about the areas of curves, that could be the opportunity for the learning of Reimann Sums and definite integrals.

Khan Academy: Integral Calculus

How do you find the area under a curve? What about the length of any curve? Is there a way to make sense out of the idea of adding infinitely many infinitely small things?

Illuminations: Hanging Chains

The illustration shows the graphs of fifteen functions. Two of them have equations y=x^2 and y=-(x-4)^2. Find the equations of all the other graphs.

NRICH: Inside a Parabola
NRICH (University of Cambridge)

A triangle of area 64 square units is drawn inside the parabola y=k2−x2. Find the value of k.
