    Applications of Maximisation and Minimisation

    A man in a rowing boat is presently 6km from the nearest point A on the shore. He wants to reach as soon as possible a point B that is a further 20km down the shore from A. If he can row at 8km/hr and run at 10km/hr, how far from A should he land?

    Confusing Chord of Contact proof by Cambridge

    That leap in the proof between the pages (...and since P lies on the tangent at B....But the first identity shows that A..) I don't understand how the first identity (and i dont even know which identity it's talking about) shows that A lies on xx0=2a(y+y0). Please clarify this proof for me

    Parametric Normals question

    P and Q are the points t=p and t=q on the parabola x=2at, y=at2 There was a question asking me to find the equation of the normals at to the curve at P and Q Then this: Prove that p3-q3=(p-q)(p2+pq+q2) By proving, I assume that I have to use the normals to work this out, but in case I assumed...
