Advanced Mathematics - Check level of accuracy
Check level of accuracy
Make sure you know how many decimal places  or significant figures are
required in the answer, or if an exact answer is required.
You will not receive full marks unless you quote the answer to the
required number of decimal places or significant figures.
It is always good practice to work through the problem to more decimal
places than you need and then round your final answer. Where you can, use
exact answers found in previous workings out.
