The line y = (a^2)x and the curve y = x(b − x)^2, where 0<a<b , intersect at the origin O and at points P and Q. Find the coordinates of P and Q, where P<Q, and sketch the line and the curve on the same axes. Find the tangent at the point P.

Firstly, for the points of intersection we need to equate the two expressions for y. Since we know that they intersect at the origin, we can immediately cancel the x values and then solve the quadratic for t...

As birds are a motile organism, we would use the mark-release-recapture method. First, capture a sample of individuals (possibly through mist netting), mark them (e.g. a wing tag or leg ring) and release. Th...
