i dont see any major difference between these two qs can someone explain / elaborate on whether there is any huge diff in the qs and how we would approach it cuz i feel like i would approach both qs in the same way:
I do these subjects:
4u math, 2u adv eng, Phys, Chem and software.
I wanna drop software.
The situation for me in the other subjects is relatively ok i.e in 4u I did mediocre and am ranked somewhere round 10 to 15 i need to improve exam technique as in the recent test I did quite some silly...
im asking this cuz a q asks to show an example of finding nth roots of a complex num with n>5
i used the example z^6 = 1 and found the roots of this.
but yh is 1 a complex number and would using it satisfy the question
for such 1 markers would working out ever be required, or is it just expected u plug into calc and write the answer cuz i feel its unnecessary but don't wanna risk it
im confused regarding this
cos2pi/3 would be cos-pi/3
but then if its an even f(x) should it become cospi/3
yh im confused regarding this concept cuz when writing anything in mod arg form i heard that the cos can absorb the negative but then
