Ok, another BOSer deciding subjects. Here's my senario: I do 12 units - english adv,maths 4u, chemistry, legal and IPT Thinking whether to drop IPT, 4u maths, or keep both. I know the scaling is by far...but i don't care. I'm sorta finding 12 units too much - just enough to finish homework. why...

Wow, thanks. That's a very good explanation repped =)

Integers less than 7000 are formed from the digits 2,4,6,7 and 9 with no repetitions allowed. If one of these is randomly chosen, find the probability that it is odd. Answer: 70/157

I'm wondering if there are worked solutions to the "engineering studies workbook" by John rochford. Stuck on some questions and annoyed...

yea that s how its meant to be grouped sorry, and i read answer wrong too, argh will fix anyway, its in the 3u cambridge textbook

eliminate parameters and hence find cartesian equation: x=t+(1/t) and y= t^2+(1/t^2) answer: x^2 -2 what shape is it?

Yes, except you missed the second part of 1). thanks

Given that (n-1)Sigma(K=0) cos(K.theta) + i(n-1)Sigma(k=0) sin(K.theta) = (1-z^n)/(1-z). 1) Prove that: (n-1)sigma(k=0) cos(K.theta) = (sin((n.theta)/2)cos(((n-1)theta)/s)) / (sin(theta/2) and (n-1)sigma(k=0) sin(K.theta) = (sin((n.theta)/2)sin(((n-1)theta)/s)) / (sin(theta/2) 2)hence deduce...

I get it now. Thanks people =)

I need help with questions 10 and 11 in exercise 4K from the patel book. Here are the questions: 10. find the modulus and argument of each of the complex numbers z and w. z= (1+i)/(1-i) and w=(root2)/(1-i) Plot the points representing z, w and z+w on argand diagram. Deduce, from the...

Here's what i think (i've tried both): Handwritten: - diagrams easier to draw + quicker (and arrows!) - usually "feels" like you will remember coz you will be writing it in the exam - allows extra notes and stuff you might wanna write on the side and still looks consistent - takes up a lot more...

I'm Criminal crab subs: English Adv, Maths 4u, Bioloooogy, engineering studies, criminal studies=)
