lmaoo i did a 3sectheta sub for that but it was so screwed then i later realised you just needed to do a u=x^2-9 sub (the thing in the squareroot - worked out very nice )
you need to submit something and just show that u made an "effort" in your submission - if you submit a document with just one word and is not related, then you will get a N award alongside a zero mark
anyone know any private hsc physics tutoring?
im after someone experienced and not someone just going through a pearson textbook, but someone who has resources and stuff.
