The size of the grade isn't as important as how good the class is overall. I_F

That curve is a cubic. Therefore its integral will be a quartic. Where the graph passes through 0 the integral will be stationary. Where the graph is below the x-axis, the integral is falling, and where the graph is above the axis the integral is rising. The further above/below the axis, the...

It's hard to tell with assessment marks what UAI you'll get, because different schools set different tasks of different difficulty. The only thing that will help is ranks and trial marks - these can be combined into a vague sort of UAI. As a very, very general rule for an 80+, you want to be...

Yes and yes. If the RBA is buying $A, there's more demand for the $A, and vice versa. Just think of direct intervention as the RBA actually going down to the marketplace and shouting at the dealer that they want to buy or sell some $A. Indirect intervention is the RBA saying "change the...

Off the top of my head, going into the cupboard transports the characters and the audience to a new, imaginative world, and the work is an allegory for Christian values (you'll find that a lot of imaginative journeys use their imaginative nature to explore and comment on the author's society)...

You need to know stuff like: Hair dryer Electrical energy -> Rotational energy of fan shaft -> Kinetic energy of air particles -> Heat energy of air particles -> etc. Basically, you take any household appliance and take the energy transfers it uses to turn electrical energy into something...

The easiest way to do it is probably to transform y = cosx - sinx into the form rcos(x+@), because then you have just the one function to graph and no ordinates to add or subtract. So: y = cosx - sinx a = 1 (The coefficients of cos and sin, ignoring sign) b = 1 r2 = a2 + b2 r2 = 1 + 1 = 2...

I'm not sure if you're required to know it, but the derivative of any exponential function is the function itself times the loge of its base (remember when you were learning about the exponential function, and you were told that the derivative is equal to a constant times the function. The...

It's from the "multiple of 6". Basically, a multiple of six is the product of 6 and another integer, and I just used P and Q as that other integer. I_F

Doing Biology and Chemistry is probably more relevant for Medicine in uni than Medical Physics. Med Physics focuses on the physics of how machines such as MRIs, CAT scans, and PET scans work. Medicine as a uni course doesn't really follow that. So while Med Physics may be more relevant for you...

To prove: 4n + 14 = 6P, where P is an integer, for all n≥1 (note that all '.' mean multiplication) Step 1: Prove true for smallest n 41 + 14 = 18 = 6P (where P = 3) Therefore true for n = 1 Step 2 - Assume true for n = k 4k + 14 = 6P, where P is an integer Step 3 - Prove true for n =...

Sigh, please read again. If the coils are connected to each other so that current can flow through, then no voltage transformation can take place. That's what I was saying - they have to have separate coils or they won't do their job. I_F

Re: is it true that private school students tend to get a higher UAI than public scho Absolutely not. Why should it be true? You can't buy a UAI. You can only work to get one. Some private schools may be better and help their students more than some public schools. Some public schools may be...

Basically, the coils don't touch and are insulated from each other, meaning that no current can go straight from one coil to the other (making the transformer useless for changing voltages). However, the coils are mounted on a common core that allows the transfer of magnetic flux, which is how...

And the 90% of developing countries that are not India or China are tremendously better off, aren't they. And advanced economies like us aren't living in prosperity and comfort. EDIT: This is sarcasm, for those who can't tell. I_F

Yeah, sorry. Fitzpatrick has that example and they did it wrong - I just checked with my teacher. Silly me. I_F

αβγ = -1. From line 4 to 5, all your teacher has done is 'added' -1, then subtracted '-3' (i.e. + αβγ + αβγ + αβγ - 3αβγ). From that line, she's taken αβ out of the first two terms, αγ out of the next two, and βγ out of the next two. Then she's factorised that using the distributive law, so...

This integration uses a second form of integration by substitution. It goes: ∫f(x) dx = ∫f(x) dx/d@.d@, where @ is usually an angle. Like in normal integration by substitution, the two d@'s cancel out and leave you with the original thing, except in a form which you can integrate. So...

That still doesn't explain why globalisation is "also it is more in favor of the less devloped countries rather than the devloped". I_F

Just handed in my Journeys folder - 7,000 words of bullshit about imaginative journeys. Got the accompanying speech tommorrow - another 10 minutes of bullshit. God, I love English... :rolleyes: I_F
