Hardest 3 unit topic (1 Viewer)

[arjun1]

was just wondering what you believe is the hardest 3 unit topic

 

[fullonoob]

varies depending on the person

 

[physicss]

For me, projectile motion.

 

[pOtentiaLeaver]

addition

 

[pi-ka-chew]

motion! xD

but the topic i hate most is sequences and series.

motion can get tough, but the more you do, the more 'standard' they seem to become... :3

for me its probably binomial stuff you find in qn 6 and 7... for now :/

some of the perms and combs , binomials arent that bad ( just proving the standard results from differentiating and integrating an expansion, finding independant terms, find greatest terms arent that bad)

personally, motion. I can't stand physics.

Projectile motion questions with 2 projectiles are hard :burn:

how is it??

you just consider the two projectiles individually and get an extra set of eqns of motion

most likely all it will boil down to is something as simple as solving simultaneous eqns to find where they collide

Not always mate.

Sometimes you may have to consider time differences or finding some fucked up equation. i.e. 2006 HSC Q6

inverse trig
SHM

thats just distance formula, and maxima / minima, yes its got a lot of terms and such, but in the end its just using distance formula and differentiating

inverse trig
SHM

what like finding the exact value of sin^ -1 [ sin5pi/3]

because most inverse trig questions are just stating domain and range of an inverse trig function, then sketching, they are easy marks if you ever get it in an exam

 

[deterministic]

is there anything really that hard about 3 unit?????
