HAHAHHAHAHA lol:haha:

also, it allows the current to remain AC and if there is only one, the thing won't work cause ur short circuiting the circuit... but u do get pretty smoke and orange sparks :p

was thinking about this but i never ended up doing a listening task.. was thinking of learning symbols for eg, S=simile and stuff like that, cause i heard that you only get to listen to it twice and then u start writting so yeah. i guess they sorta save time and allow u to jott down more

$ first find the concentration of the sodium carbonate solution you made$ c_{Na_2CO_3} =\frac{moles}{volume} $then write a balanced equation of the reaction between the Sodium Carbonate and the hydrochloric acid% Na_2CO_3 + HCl \to 2NaCl + H_2O + CO_2 $ now work out the moles that is in that...

or what you can do is draw 9x^2 + 6x . and then shift it up by a value to make it positive definite. then square root the value of the shifting value and then add a plus minus sign in the front. f(x)= 9x^2+6x x=\frac{-b}{2a} =\frac{-6}{18}=\frac{-1}{3} $at$ x=\frac{-1}{3} y=-1...

ur supposed to post a new question now

real :(

$ the curve is symmetrical about x=1 f^{-1}(f(a))=f^{-1}(f(b)) \frac{a+b}{2}=1 \therefore b+a=2 \therefore b=2-a $ hence f^{-1}(f(b))=2-a

still have 4 things on my to-do-list.... would gladly love another week, i guess imm gonna be as busy as hell the first week back at school:bomb: totally agree with the SC lol. +1

lol, asain 5 FTW

when i read the thread title, i thought someone on BOS created a web browser.... but firefox FTW

\int_{1}^{2}x.dx = \left [\frac{x^2}{2} \right ]^2 _1 = 1.5 Question: $find the real numbers A and B so that$ \frac{A}{1+i}+\frac{B}{1+2i} =1

they are equal in magnitude, but the sign of the arg, or angle, for the conjugate is minus, because it is below the x-axis.... ill give u an example. $find the argument of the point 1+i and then find the argument of the conjugate and then come to a logical conclusion (3 marks :p) arg(1+i)=...

that bit comes from looking at the diagram... ill draw one up.. where x-iy is the conjugate of x+iy

arg(\frac{1}{z})= arg (z^{-1})=-arg (z)=arg (\bar{z}) by looking at an argand diagram, , if you plot the point x+iy to be some where in the first quad, the point x-iy will have the same side ratios and hence magnitude of the angle is the same, but it is just flipped into the 4th quad... hope...

lol whats the batman sped doing at 2:45

product of roots?

well, the magents need to be electromagnets so you can switch the phases and make it a 'moving' magnetic field.... do u need to make one that works or just a model of one...? cause they are pretty complex suff! the only way i can see it work is using switches to enable and disable the phases...

heat is kinetic energy yeah? when u heat water, the water bubbles and moves, thus you give it energy (conservation of energy) and when u give it energy, it excites the drink making the molecules move alot (the same effect as heating the drink).
