Orientation starts tomorrow :) who's going tomorrow?
if not, then when are you going for orientation?
I'm going tomorrow so I guess I'll see you people there :)
This is from Cambridge 4 unit ex 3.2 question 7
P(a cos θ , b sin θ) and Q(a cos ɸ, b sin ɸ) lie on the ellipse x^2/ a^2 + y^2/a^2 = 1
a) In PQ subtends a right angle at (0,0) show that tanθ tanɸ = - a^2/b^2
b) If PQ subtends a right angle at (a,0) show that tanθ/2 tanɸ/2 = - b^2/a^2
Hi I'm Jona Domingo
I'm doing 3/4 unit maths
I live in Plumpton but I can travel to Parramatta Library or Blacktown Library.
I want to go over the 3 unit and 4 unit course just to get the exposure for the sorts of questions and stuff
If anyone can tutor me
call or sms me at: 0404 426...
can someone show me the working for the following questions...?
1. On an argand diagram the points A and B represent the complex numbers z1 = i and z2 = 1/√2(1 + i). Show that arg(z1 + z2) = 3π/8
2. Use the vector representation of z1 and z2 on an Argand diagram to show that
a) If |z1| =...
