nah everyone doing unsw med is pretty cool

yes thats the one z1 - z2 +z3 - z4 = 0 rearranging, z1 - z2 = z4 - z3 taking mods of both sides, |z1 - z2 | = |z4 - z3| so one pair of opposite sides are equal. repeating, |z3 - z2| = |z4 - z1| so the other pair of sides are also equal (remember this defines a parallelogram) therefore if...

are u happy with help along these lines?

8) gather terms on both sides and take mods, eg: |z1-z2| = |z4 - z3| that means opposite sides are equal. repeat. remember multiplication by i for the square.

yes the exam should comply with the syllabus you should complain if it doesnt although u wont always succeed (remember chem from last year sgs boys?)

just to be pedantic, q1 isnt ALWAYS integration: look at the 82,83, 89 and 90 papers

cheers to the admin for rearranging the forum

remember in strong acid base the change in pH is very steep, so rapidly changes from high to low pH (is that the right way round? ). so phenolpthalein can be used as an indicator.

the 2x squashes the sin graph by a factor of 2 the minus sign flips the graph in the x axis. the 1 shifts the graph up one. substitute in pts if ur really having trouble
