20.3


No. It was 20.4 cm mate

Anyone else get last question x =1/3a pi and x = 4/3a pi ? Thought it seemed too simple for four marks

Yes I put 60 degrees and 240 degrees instead of in radians, how many marks will I lose ?

What the actual **** was question 9?!

Anyone else get a =5/3?


yeah the whole paper was fine until that last question i didn't know what to do!

From the top of my memory these were the questions : 1.Find ab (2) ii. Find bc (2)2. 54 in radians (2)ii. Find r (3)3. Binomial (4)ii. Coefficient (2)4. Single log (2)ii. Log=2 (4)5. Integrate (3)ii. Find a (4)iii. Infinity to 0 (1)6. Arithmetic (3)ii. Geometric (2)ii. Find N (6)7. Remainder, quotient (3)ii. 3 linears (3)iii. Differentiate (2)Iv. Area under curve (4)8. Translation (2)ii. Stretch (2)iii. Sketch exponential curve (3)iv. Logs (3)V. Trapezium (4)9. Period (1)ii. Find a and X (3)iii. Tan = root 3 (3)

I got 38 and 38 is correct as I checked it. Anything less than 38 didn't work.

38 is correct.
everyone please add in so we can make one on a document or somethig, but this is what i remember and i got
10cm, 5.4 something? for first
two was 3pi/10 and radius 20.4cm
third question was expanding (3+kx)^3 then k in part 2 was +/-1/root3 i believe

four was logs logbase 3 (x^2/x+4)
then x=12 i think
five was integration dont remmeber values
5bii was 4
6 k was 91, n was 38 cant remember part ii
7 was x^2-4x+3 and roots -1 1 and 3
and integrated it between 3 and 1 think answer was 512/15 or something
8 was transltion +2, then stretch 1/9 in y, sketch graph and x for y=180 was x=6.something?
9 was 2pi/a, a=5/3 and k=root3/2 and i think last part was x=pi/3a and 4pi/3a
