Mathematics Extension 1 working out in Physics (1 Viewer)

[PC Dandy]

It has occurred to me that all projectile motion questions in Physics can be solved using the Maths Extension 1 methods of integrating from the horizontal and vertical acceleration equations a_x = 0 and a_y (aka g) = -9.8, instead of the prescribed equations on the formula list.
Has anyone doing both Physics and Maths Extension 1 attempted using such methods in a Physics exam?

yes I did it in the 1/2 yearlies and my teacher didn't like it. I got the question out but he explained if i dun goofed up then I would get zero for the whole question. It is much easier just to sub into those formula's and whatnot rather than deriving from scratch. There wasn't enough paper either lol

Never use MX1 in HSC Physics or Chemistry. You won't get the marks if you have one simple error that stuffed you up.

Work with the equations given on the formula sheet and remember all other formulas that are related but not on the sheet.

Thanks for your replies. I had a feeling that such methods may not be allowed when looking at the marking guidelines of past papers.

You can use it, but as said above, you'll lose all marks if you make a mistake.
But the formulas given to you are the same formulas you would derive anyway, so deriving them is a wast of time.
