Wow thank you guys so much. Is it also true that at Sydney Uni, you can choose between Applied Maths and Pure Maths? Only at Sydney Uni?

wow thats cool. Thanks for that. I just thought that Advanced Mathematics learn more maths that harder? After finishing the degree, will it even (Advanced Mathematics) on the certificate?

Hi guys, I really love maths and actually, the only reason why I am considering on choosing B Science is so that I can major in Mathematics. Is this a good idea? What alternatives would you recommend? In first year Science, I hear that you do a bit of everything like chemistry and other...

Hi guys, I have been given an assignment to make a video demonstrating a model of a solar cell. The model must include: Connnection to resistors Demonstrate how solar cells work Components within a solar cell Electron hole movement P-N junction If you can, would you be able to provide...

A Bachelors in Science (Maths), am i able to move from that to Advanced Mathematics in the first year? Say if i finish my Maths degre, what possibilities does that open up for a career? Where could i work? Examples.

Thanks Carrotsticks, but shouldnt the thickness be delta y considering that the slice is taken perpendicular to the y=axis?

Hey guys, Can you please solve this question for me? It goes on the lines of: The base of a circle has the equation x^2 + y^2 = 9. Find the volume of the solid if every cross section perpendicular to the y-axis is a square with one side in the base of the circle. Thankyou so much!

Would someone be able to send me a copy of the Sydney Tech recent Conics Exam? Thanks so much.

oh i see thank you so much. How do you do it so quickly in your head, do you use factor/remainder theorem and then use long division? :O

Spiral Flex, How can you just say that the zeroes are +- 1 and +-3? Thats the only part i dont understand. Thanks again.

Hello, How would i approach this question and how would i solve it? Please show all working out and reasoning. P(x) is a monic polynomial of degree 4 with integer coefficents and constant term 3. One zero is 'i' , another zero is rational and the sum of the zeros is negative. Factorise P(x)...

ohhh i see now. Thank you so much.

i tried to use AAEldar's first method but i only got 1 solution: 2(cos(0)+isin(0))

whoa, Spiral Flex, your way seems so complicated. I just used what AAEldar said and factorsed z^3-8=0 then use quadratic formula for z. Apparently, i got 3 solutions, they were: 2(cos(-2pi/3)+isin(-2pi/3)),2(cos(2pi/3)+isin(2pi/3)) and 2(cos(0)+isin(0)). Are these correct? Btw how do you...

My teacher has given me this year's complex number questions. Would you be able to do them so that i can check my solution? a) Let w=2-3i and z=3+4i i) Find (conjugate)w + z ii) Find |w| iii) Express w/z in the form a+ib, where a and b are real numbers. c) Find, in...

Thanks but does staying ahead of the class mean to self teach myself few concepts?

Your soo far ahead, i've merely just started... how much people are in your 4 unit class?... over here is just 2 including myself.

Currently, im doing Complex Numbers, it seems pretty simple enough. I feel behind because I just learnt modulus and argument form of complex numbers. My questions is; What parts/topics are you on now in your 4 unit class? Much appreciated, Kayven.

Is this a complex number question which some-what relates to sequences and series?

The cost 'c' (in dollars per hour) of running a boat depends on the speed v(km/h) of the boat according to the formula: C=500+40v+5v^2 on a trip of 100km from port A to port B, what speed will minimise the total cost of the trip? How should i approach a question like this? Show all working...
