Guys it was a seriously easy exam, all the other years were unbelievably hard. The only question that got me was the torque one and the "gyration constant", i just lol'd since i had never seen that in my life.
Some dumbass at my school (like iQ of 'mystery mark' equivalence) didn't attend a single engineering class in yr 12 and rocked up to the HSC exam asking people how he could drop the subject last second....
We had someone caught in ext. 1 exam, many lolz when we heard how "subtle" it was (he like totally turned his body to have a "peak" at the guy next to him)
Re: Einstein's going down, physicists!
I believe that special relativity meant that a body of mass couldn't accelerate to the speed of light, it didn't mention anything about:
a). already going faster than the speed of light (tachyons);
b). anything about energy travelling the speed of light...
Lmao i was the same as you, worrying about things that look hard. Integration is easy when its explained (take my word for it) there is a very simple process you go through and thats it. 4 unit just expands on it a little more, but nothing to be worried about.
At my school, captains, vice, etc. is sooo rigid some teachers point it out, we had a few ext. 1 math probability questions were the selection of school captancy was rigged lol
I dont understand why sine, cosine and tangent are so difficult (unless your doing the taylor series, where it gets confusing) In general you really only have a few conditions you must follow, if your remember them then your sweet for the test. And no matter how much they try and confuse you...
