I know that med schools have alternate rural and indigenous pathways but I've also heard from my tutors that some universities have a bias when choosing applicants for medical school - i.e. choosing fewer asians/indians (perhaps maintaining a quota of other backgrounds hispanic, anglo-australian...
prove\ that\ the\ max\ value\ of\ |e^{i\theta}-2|+|e^{i\theta}+2|\ is\ 2\sqrt{5}
How would you solve this? Apparently there are methods using geometrical graphing or using trig algebra - feel free to solve outside these methods tho.
Much thanks! :D
Is there a technique that means opening line for "Maman died today." (The Stranger CAMUS)?
Other macro/medial/micro techniques appreciated for quote
thanks1
2. Show that \left(1+x^2+2x\right)^{2n}=\sum _{k=0}^n\binom{2n}{k}x^{2n-k}\left(x+2\right)^{2n-k}.\:
3. It is known that
x^{2n-k}\left(x+2\right)^{2n-k}=\binom{2n-k}{0}2^{2n-k}x^{2n-k}+\binom{2n-k}{1}2^{2n-k-1}x^{2n-k+1}+...+\binom{2n-k}{2n-k}2^{0}x^{4n-2k}.

How many arrangements of the letters in the word ALGEBRAIC are possible if the vowels must occupy the 2nd, 3rd, 5th and 8th positions?
ALGEBRAIC is a 9-letter word
Vowels are AAEI, consonants are LGBRC
I would solve this using cases:
AA in 2rd, 3rd - e and i in 5th, 8th, alongisde 5 consonants...
If\:U_1=\int cot^nxdx,\:show\:that\:U_n=\frac{-1}{n-1}cot^{n-1}x-U_{n-2}
I'm going to take a while to do latex so here's a picture of my working so far instead:
I don't know how to work the integral on the last step.
Maybe some hints? (use spoilers)
Thanks so much for the help!
on such graph, impact velocity is 10sqrt21 from formula v^2 = xdot^2+ydot^2.
I was just wondering, how do you know if we take the positive (as in this case) or the negative velocity?
Thanks so much for your help!
[edit:]
Wait... maybe the answers supposed to be negative 10sqrt21 from...
It is known that z^{3}+\frac{1}{z^{3}}=w^{3}-3w.
from this and the quoted solution above (|w^{2}-3|\ge|w|^{2}-3), prove by contradiction that |z^{3}+\frac{1}{z^{3}}|\le2\ \to|z+\frac{1}{z}|\le2.
Assuming that |w^{3}-3w|\le2\ \to|w|\le2 to be true,
LHS: |w||w^{2}-3|\le2 =...
What is this course about that's different to specialising in a clinic after MD? Do you have to take it if you want to become a surgeon? When can you even register to take this course (After Undergrad Med Science? After MD?) [general confusion]
I'm a pretty skinny (decently low body fat BMI 18) guy and I'm getting stomach creases from poor posture - I sit down for most of my day and mainly do lots of work on a laptop or with physical notes. Any tips for better posture and fewer stomach creases?
Evaluate \int _0^{\frac{\pi }{4}}\:sec^4x
I know if I(n) = \int \:cos^n\left(x\right)dx
then I(n) = \frac{1}{n}sin\left(x\right)cos^{n-1}\left(x\right)+\frac{n-1}{n}I\left(n-2\right)
but how would we adapt that to sec^4x?
Thanks for the help in advance!
Let z be a complex number.
Let w=z+\frac{1}{z}.
Show that \left|w^2-3\right|>\left|w\right|^2-3.
LHS = \left|z^2+2+\frac{1}{z^2}-3\right| = \left|2cos\left(2\theta \right)-1\right| = 4cos^2x-2-1 = \left(2cos\theta \right)^2-3
RHS = \left|z+\frac{1}{z}\right|^2-3 = \left(2cos\theta \right)^2-3...
