Re: Physics Tutoring For HSC 2013 -- Starting Term 4, 2012 [FILLING FAST!] Looking at the results of your students, there must be something in those cupcakes :P Are they sold separately?

Yes, have a story ready, or at least a plot that complies with the Area of Study.

What is your school rank, and where are you ranked in your cohort?

\begin{align*}&Q10(a)\\&y=cos^4x\\&y'=4cos^3x \cdot~-sinx\\&=-4sinxcos^3x\end{align*}

But isn't that different to proving logb(x)=y then b^y=x? Logs were invented by John Napier as assistance in multiplication, and were essentially simple calculators. How can you prove a concept created by man, not discovered by man? (Unless I am dead wrong, if so im sorry)

Don't know chemistry, but that 'triangle' is delta. Δ

Excel is just like or a bit above mif in terms of difficulty. Cambridge, Fitzpatrick and terry lee are best.

makes sense. Hopefully they are more interesting.

ah kk just looking at the HSC syllabus it looks like electricity is needed for M&G a fair bit.

The syllabus says its assumed knowledge, but how well do you need to know it?

Yep that proves those two are perpendicular to each other. Then show the third line crosses both of them to form vertices of a right-triangle.

Sorry I should have specified, the Ext 1 papers are maths.

If the results were accurate, that means that you need to add: -The number of people with the flu and the test indicated so + -The number of people without the flu and the test indicated so. So 72+256=328. Then to find as % put it over 347, which is equal to 94.52449568%, rounded to 95%. So (C)

Isn't it 2?

Perpendicular bisector means the line perpendicular to the line passing through those points, but also goes through the middle of those two points. So find the midpoint of the two points [ (2,?) ] and then use the point gradient formula. (are you sure the gradient is 1/2?)

Correct.
