Probability is the most logical topic ever. I don't know why people hate it so much..

Re: Don't understand concept of P(AB) in non-mutually Exclusive Events - Probability Conditional probability isn't in the course. Don't worry about it until uni.

No air resistance, 'g' is constant (otherwise the trajectory would not be parabolic) and the speed of the ball is much less than the speed of light (otherwise you'd need to consider relativistic effects) t=2u sin theta / g = 2 * 10 * sin30deg / 9.8 = 1.02 s

That head teacher wouldn't possible be of the name Monika Khun, would it?

Yeah. I've seen a bit in 1st year physics at university.

Density isn't in the course... It's interesting though. You do a bit of it in 1st year physics.

2b=10 so b=5 a=4 (from a diagram, at position PS = PS' figure forms a 3,4,5 triangle) An ellipse with foci at (0,3) and (6,3) and major axis length 5 units and minor axis length 4 units and y axis is the major axis.

If z_1, \ z_2, \ z_3 lie on a circle through that passes through the origin then prove that the points representing \frac{1}{z_1}, \ \frac{1}{z_2}, \ \frac{1}{z_3} are collinear (ie. lie on a straight line). I have a solution for this that uses one circle geometry theorem. I'm sure there's a...

Nice... Just curious though, what editor do you use for LaTeX?

Could be a one marker in the earlier questions. You never know.

Well I don't mind the font. But imagine in the 1960's when everyone had to use that book for HSC maths. Not a pretty sight since everyone I know depises the font in Coroneos :P

I would probably opt for Coroneos. But that's just me probably.

Prior.

Yes it is possible. Tension in the rope is the same throughout the rope (provided that it's inextensible).

Sorry I made an arithmetic error. Serves me right for doing it in my head :P

Draw a diagram showing the forces on the mass (ie. weight, mg and Tension, T) and indicate the positive direction. If upwards is positive then: 0.5 * 1.5 = T - mg T = 0.5*1.5+1.5*9.8 = 15.45 N upwards BTW this is in the preliminary course.

Where are these questions from? Just curious..

Breaks are a waste of time in my opinion. But that's just me. Last semester I think I had too many. You never work in them and get side-tracked. I made some friends though...

lol I think that's a spambot :P
