from wikipedia: Bhaskara II tried to solve the problem by defining (in modern notation) .[1] This definition makes some sense, as discussed below, but can lead to paradoxes if not treated carefully. These paradoxes were not treated until modern times.
Well remember the Summer Internship Presentation. The first presentation ever, followed by that first question tht you were, ahem, 'supposed' to ask. NO frankly, you were.
Yes, I was. And as an advice to anyone who stumbles across this piece, do not, and i repeat, DO NOT ask the presenter what his objective of the project was. I mean its okay if he didn't have one or he wasn't clear or even if the professor who penalized you for that agreed at the end of the presentation. Just do not be a smart-ass. The world doesn't like them; or at least it doesn't prefer any smart-assery from my kind.
The best thing is to not listen to the codswallop (yae HP!) and simply fish out that competition guide and solve those entrance exam problems, which i am terrible at, at the moment.
Lord save the meek. Oh yeah, He sent the professors to do that.
