looking for alibrandi the book for physical journey essay ORT?? or is the book already part of hsc course??

can someone explain this and answer the questions below: 1. Brielfy explain why an exchange rate can move in the opposite direction the the TWI. 2. Explain the likely impact on the Aus's BOP of the decline in the TWI.

6. a) Show that if y=mx+k is a tangent to the rectangular hyperbola xy=c^2, then k^2+4mc^2=0 b) Hence find the equations of the tangents from the point (-1, -3) to the rectangular hyperbola xy=4 and find the coordinates of their points of contact. a) i can do, its just the discriminant...

Cambridge. Exercise 6.1 q7 Use the method of slicing to find the volume of the solid obtained by rotating the region: enclosed within the circle (x-1)^2 + y^2 = 1 about the y-axis more stuck with the integration, prob aint too hard or easy im just missing something

Fitzpatrick Exercise 25(e) q4 A body initially at room temperature 20 degrees, is heated so that its temperature would rise by 5degrees/min if no cooling took place. Cooling does occur in accordance with Newton's Law of Cooling and the maximum temperature the body could attain is 120 degrees...

reduction formula questions, seems easy but im gettin real close but not the answers both Cambridge 5.5 17. If In = ∫sinⁿx dx for n≥0 show that In = -1/n cosxsinⁿֿ¹x + (n-1)/n In-2 for n≥2 18. If In = ∫secⁿx dx for n≥0, then In = 1/(n-1) tanxsecⁿֿ²x + (n-2)/(n-1) In-2 for n≥2...

19. P(2ap, ap^2) and Q(2aq, aq^2) are points on the parabola x^2=4ay/ The Tangents at P and Q meet at R, and R lies on the parabola x^2=-4ay. (a) Show R coordinates (a(p+q), apq) (b) Show that p^2 + q^2 +6pq = 0 (c) As P and Q vary, show that the locus of the midpoint of the chord PQ is the...

question 6 exercise 3.4 cambridge: (a) Show that if y=mx + k is a tangent to the rectangular hyperbola xy=c^2, then k^2 + 4mc^2 = 0 (b) Hence find the equations of the tangents from the point (-1,-3) to the rectangular hyperbola xy=4 and find the coordinates of their points of contact...

sounds like a stupid question but how are we meant to use ross gittin articles??? are his pts and theorys on economics valid for essays?? or are we meant to quote his beliefs and statistics?

The polynomial P(x)=x^3+ax^2+bx+6 (a,b real) gas (1-i) as one zero. Find a and b and hence factorise P(x) over the complex field C. i know u have to use the complex root conjugate, i can find a and b, but i just cant seem to factorise. thanks

Find : integral of 1/ (5+4cos2x) dx Find : integral of xcos(x^2) dx anyhelp appreciated thanks!!

how do i do a question like this If In = integral (tan^(n)x dx for n greater than/equal to 0, show that In = 1/(n-1)tan^(n-1)x-I(n-2) for n greater than/equal to 2. Exercise 5.5 q15 i think its cambridge

i have physics excel as supplementary but finding it not as useful for answering sylabus points and writing summarys i am planning on gettin another book, jacaranda or hsc success which book is more suitable for writing sylabus based point summaries???

question : Sketch the following showing all asymptotes, intercepts and important features, y = root [(x-1)(x-2)] / (x-3)] thanks
