Thanks for ur help. :D I understood alr.

How do u know gradient of MB is y/x? Since M(0,y1) and B(x,y)? The gradient depends on coordinate M also? I mean it depends on y1 also? And then for the Pythagoras theorem, can u explain tat?

Does anyone know what's the solution? :) A man M walks along a pier, represented by the positive y-axis, pulling on a boat B(x,y) by a rope of length L. The man is initially at the origin O and the boat is initially on the x-axis, L metres from O, The man keeps the rope taut and the path...

Thanks :D
