Find the following in x + iy form: (3-4i)^5 ----------- (4+3i)^3 Im gettng 24-7i, but the answer says 24 + 7i??? ITs out of the fitzpatrick exercisess... Thanks

Nope the question is simply like that, ridiculous isnt it :(

Ok in teh Fitzpatrick test book, there are a few "show" questions which to me seem quite ridiculous; ex 31(b) Question 32. e.g. Show, that for z1,z2 and z3, where z = x + iy z1(z2.z3) = (z1.z2)z3 Do you simply let z1 = x + iy, z2 = a +ib..... Expand and then collect like terms to prove...

Anyone got a copy of the 2008 MEX1 to upload? Thanks.

Its does not mention planks and wheel* till part (iii), next time you use yours ;)

Yep thats how I thought you can attack the question. Assume they're tangents, draw a perpendicular line to each tangent, sum of all areas, factorise and you got your proof... Thanks.

Hey guys. Just curious. Whats the hardest four unit question you have ever seen. I mean not only teh HSC, but trial papers too. Please quote this question and briefly describe what it asked. Thanks.

Hey. For question four of the 2008 HSC paper, it said the circle touched all three sides of the triangle. Does that mean you can assume the sides of teh Triangle KLM are all Tangents to the circle. Need that for the second proof... What is another way to do it??

Solve the following equation: x^2 - 2isec[theata]x - 1 = 0 Im getting x = i(sec[theata] + Tan[theata]) and x = i(sec[theata] - Tan[theatre]). Is this right? Or is there a way to simplify it even further??? Thanks.

Hey. Can I ask, I understand why you did all that work after "Also", But what made you do the work before that??? Why did you go that path? Thanks.

Hey there. What would be the fastes way to do this question??? Find thelength of the focal chord that meets the parabola x^2=-12y at (2,(-1/3)) Basically I found the equation of the line, Found the second intercept and then determined the length. This method can be quite long for such a...

Hey. I was just wondering. When does everyone have their 4-unit classes? What day and time? Ive heard some schools are so tight on time that they have them on Saturday Mornings....

When you have inequalties involved, usually you have to test; especially if theres more than 1 absol value in teh equation. Although, if you do a lot of examples, you will find that certain types of questions dont need testing. You also have to test an equality like this |z+3| + |z-9| = 5...

Ok I get everything up to the boundaries of 0< t< 180 parts. Can someone explain further please? dont understand how you getting those forumulae from 0< t< 180?.

Hi. Lately Ive been transforming a pair of parametrics into Cartesians. I've been a little confused when it comes to a qustion that has restriction on y-values instead of x. I work out the solution but when I look at the answers, the answer is usually a different equation. For example: Solve...

Hey there. Ok basically I have a really bad habit of making silly mistakes in an exam situation (and sometimes even outside an exam). Im talking every test I do I make silly mistakes, ultimately costing me marks. My question is: How can I learn to improve from this flaw. I try to calm myself...

Holy...:eek: What the hell is this. I hate permutations/combinations. Questions can be rather anoying as they take too long (LIKE THIS!!!) and its easy to make a silly mistake

Ook thanks. So yeah they can be quite useful in that when you finish a topic, you can relate to specific questions. Although, it probably wont be a good idea because from what I know, exams tend to stick more than 1 topic in a question...

So sick of year 11s doing that?? No need to rage over the fact that you strugle to learn things on their own. He can get ahead, why do you care?

Hey I was just wondering, do past paper books organise questions based on topics or the papers themselves. What Im trying to say is how are the books organised, do they simply order the 2003, 04, 05, ..... papers in order. Or do they have sections for Complex numbers, polynomials etc with a...
