American Independence Day

This is just to say, I have only the utmost respect for Darren for taking such a courageous choice, not to mention the location in which he did so.

What the heck differentiation is killing me (so is kinematics but that's beside the point). I simply cannot understand the composite function rule from the examples given. For example, how is the derivative of y=(x^2-9)^0.5 equal to x/[(x^2-9)^0.5]???

Never mind that, I figured it out. Heil mein Wiki (too obvious?)! So why does the same rule apply to y=1/(7-3x) ... 3/[(7-3x)^2] aye?

Should really be doing English IST and Science homework, but cbb, and after that studying NQE material.

To do these holidays:

• Find work experience
• Find a service AND skill (a bit late, I know)
• Revise maths... a lot (history and geography can go di- jks)
• Revise science to an insane degree
• Run for more than 4 hours these holidays
• See a chiropractor and/or physiotherapist (how much do they cost, Idk)
• Finish reading Art of War, Communist Manifesto, Meditations, Aeneid and all those other classics on my arbitrary bookshelf
• Investigate year 11 course opportunities
• Learn that fingerstyle (and or otherwise learn fundamentals of playing)
• Acquire usable fingernails for strumming (.....)
• Finish homework (obviously)
• Don't go blind from LCD overuse (somehow no longer have excellent vision)
• Other nondescript tasks which I remember not

Protip: you know that annoyingly useful Fibonacci sequence? Apparently there's a formula for any number assuming u₁ = 1 and u₂ = 2:

u_n = (1/sqrt(5))*[(1+sqrt(5)/2)^(n+1)-(1-sqrt(5)/2)^(n+1)]  (Hope you people can read that)

Independence day? We don't celebrate that here. Goodnight.
