11a) (i didn;t find the equations of the tangents, just the gradient at those points. I might do the rest of the questions later when i have time.
Also, out of curiosity, where did you get these questions from? this seems more like a 4 unit question to me.

The extension sections are only really relevant to those people thinking of doing 4 unit in their HSC year. They are not in fact, like sikhman said, in the 3 unit course.
