i guess u solved it wrong though u removed log correctlyI did the same

ln(x+1)=2 ln(x-1)

ln(x+1)= ln[(x-1)^2]

(x+1)= (x-1)^2

but i was getting x as 7 or -6

not 2.3, what did i do wrong?

u vl get a mar for this =P

The answer to the binomial question was 1-x+(1/2)x^2

uhm weren't there 3 stationary points in q 6, as in pie/2, pie/12 and 5pie/12?Q1. 2.30

Q2. 1.32 rad

Q3. 1-x+(1/2)x^2

Q4. 201 and 330 something

Q5. y=-ln((3/2)-(1/2)e^2x)

Q6. two stationary points ; max point

Q7. -1/2 + i 1/2

Q8. ---

Q9. y=x-1 ; pie/4(e^2-1)

Q10. distance =6

correct me if im wrong

Yar i think that u guyz have quoted the question wrongly as evn by solving the above equation, u get answer as 0 nd 3 so hence i belive that Q 1 above is wrongly quoted here!

And my answer to binomial expansion Q was

------ 1-x-(3/8)x^2

I cnfirmed it with guyx at the center yesterday and all people said k yahi tha! :/

Can nyone else cnfirm?

No, there were two and the point was minimum point, according to what i solved.uhm weren't there 3 stationary points in q 6, as in pie/2, pie/12 and 5pie/12?

I think due to range bcoz range was less not 360,

though i dont exactly remember!

Yes 3 stationary points!!! pi/2 was fr cos inverse of 0

Agreed, 3 stationary pts for me too, got same answers as that other fella posting the answers! I will solve the paper with my tutor in a few hours so I can write the answers here if you want afterwards guys!Yes 3 stationary points!!! pi/2 was fr cos inverse of 0

Cux if u solve the above equation u dnt get a quadratic equation and answer comes as 3 or 0 so hence

I think that it is wrongly quoted! Please see fr once!

yes i got the same answer as far as i rember!Yar i think that u guyz have quoted the question wrongly as evn by solving the above equation, u get answer as 0 nd 3 so hence i belive that Q 1 above is wrongly quoted here!

Can nyone else cnfirm?

and wat was your volume?yes i got the same answer as far as i rember!

I have the exam paper infront of me right now, it says 0 < x < pi0 < x < 1/2 pie

so only 2 stationary points

there were two stationary points.Yes 3 stationary points!!! pi/2 was fr cos inverse of 0

quote the bionomial questionI have the exam paper infront of me right now, it says 0 < x < pi

yes plz post them as soon as ur tutor solves it!Agreed, 3 stationary pts for me too, got same answers as that other fella posting the answers! I will solve the paper with my tutor in a few hours so I can write the answers here if you want afterwards guys!

Expand sqrt 1-x / 1+x in ascending powers of x up to and including term in x^2quote the bionomial question

will do, no worries!yes plz post them as soon as ur tutor solves it!
