differentiate x3 using first principles.

i) (a+b)(a2-ab+b2) ii) RHS= 2-2sin@cos@/2 = 1-sin@cos@ LHS=(sin@+cos@)(sin2@-sin@cos@+cos2@)/sin@+cos@ = sin2@-sin@cos@+cos2@ = 1-sin@cos@ LHS=RHS .'. (sin3@+cos3@)/(sin@+cos@) = (2-sin2@)/2

1) there are a few topics in 3 unit which aren't in the book, i think parametrics is in the year 11 book

Middle to RHS isnt trig, its just 2sin and -2sin cancelling. leaving a minus which goes infront of b/a.

(x+1)(x+4)(x+2)(x+3) = 8 (x2+5x+4)(x2+5x+6)=8 let u = x2+5x (u+4)(u+6)=8 u2+10u+16 = 0 (u+8)(u+2) = 0 u = -2, -8 x2+5x = -2 (quad formula) x= (-5 + sqrt17)/2, (-5 - squrt 17)/2 x2+5x = -8 (quad formula) doesnt work .'. x= (-5 + sqrt17)/2, (-5 - squrt 17)/2 not sure if this...

= (x3)2 - (8)2 = (x3 - 8)(x3 + 8) = (x - 2)(x2 + 2x + 4)(x + 2)(x2 - 2x + 4)

metallica. master of puppets and ride the lightning are fucking awesome albums.

no order 1. Nirvana - Nevermind 2. Nirvana - Bleach 3. Nirvana - In Utero 4. Nirvana - Incesticide 5. Black Sabbath - Paranoid 6. Black Sabbath - Master of Reality 7. Metallica - Master of Puppets 8. Metallica - Ride the Lightning 9. Metallica - ...and Justice for all 10. Black Sabbath -...

\ LOL

Metallica - Creeping Death

yes its compulsory

cause it wasnt about those subjects but really, english is gay

does angle OED = 30degrees and angle ODE = 20degrees?

there are a few 3 unit topics in year 11 cambridge but most of the 3u are in the year 12 book.

i put D :( only because from the info we were given it didnt say much about cities and light but it said stuff about altitude so i put D

cause english is bullshit

biooooooooooooooooooooooosphere

cant be right angle correct for the rest i think

yeah you are right studentcheese its 49/sin33
