find the area btwn y=sinx and y=1/2 for this question what are the limits? 0-30, 30-150, 150 to 360 or 0-30, 30-150, 150-180, 180 to 360? also do you have to absolute the answer? if so how do you absolute things such as -(5/12)pi + root3/2 and also how do you solve the question thx in adv

differentiate xtanx the answer books answer is xsec²x + tanx but my answer is xsec²x. was it a error in the book? thanks

what is the offical BOARD OF STUDIES date before you cannot change prelim subjects not the school. Thanks in advance

find the equation of the locus of a point P that moves so that PA is twice the distance of PB where A=(0,3) B= (4,7) my answer is different from the answer book dont you solve it as PA = 2PB

to find the stationary points for y = (3x-1)(x-2)^4 isit essential to differentiate then expand the whole thing out. then testing for a factor then using long division? can som1 put solution up please? thx in adv

yea i know what both of you are saying but "It just means by considering the first derivative (the stationary points, and the point of inflextions) and the second derivative (the nature of them) draw the curve y=f(x)" they are not asking you to find that.. they have the 2 points and they want...

second derivative and applications of calculus (solved) I have previously done these question but now im not sure how to doo it........ question : By considering the sign of f'x and f''x sketch the shape oft he cure y=f(x) in the give domains a)y=x^3 from x=1 to x=3 the answer is the 2...

thanks again but the yellow one is easier than the green one isnt it? the green one is insane.

sumtimes the chapter names differ and im lazy:p do u happen to hav ethe year 11 one too?

Thanks man. Is there other text book chapters that i should ask for? ive got the fitz one and the 3 u book and now cambridge. i think im only leaving out maths in focus

My school uses the "New Senior Maths" and orange "3 unit" book. We were given an outline for what chapters for each topics e.g Integration Ch18. Could anyone (using Cambridge textbook at school) post the outline for what chapters or pages for each topics. Thanks in advance

thankyou for adding in what i missed out. i was in school no time to complete... the bloody teacher was like " dont you understand english? You were told to turn off the comp" ... bloody ass

YBK while your at it you might want to know: f'(x) = y = dy/dx (all notations) = m (gradient) = 0 (at stationary points) f''(x) = second derivative - shows the concavity of the curve when is positive it is concave down i think i was and concave up for the other one.. or the other way round =...

in maths there was a question about 5 tubs of icecream.... if you chose 2 how many diff combinations are there... on the calculator i put 5P2 instead of 5C2..... i did permutations instead of combinations....

i was wishing the science was not so much knowledge based but more applied science.. guess what.... heaps of knowledge based...hope i go ok

klaw mr, u cud be kinda nicer. Tu17 i believe you should question yourself isit because your lazy or incapable. It is better doing general maths than having trouble with your 2u adv. If your lazy like me then perhaps get you parents have a chat with your school. Yr 9 and 10 maths was easy. I...

A=(-1,-3) B=(2,4) P=(x,y) then m of AP = (y+3)/(x+1) and m of BP = (y-4)/(x-2) perpendicular at -1 therefore m of AP x m of BP = -1 [(y+3)/(x+1)][(y-4)/(x-2)]=-1 y²-4y+3y-12/x²-2x+x-2=-1 -x²+x+2=y²-y-12 x²+y²-x-y=14

I dont think you use 2 point formula. it doesnt really make sense. the 2 point formula will just give you the gradient of the line joining the to points but not the locus of the point.

well im a year 10 in my class we do stuff same as year 11 in our school. we did diff in the beginning of the year so.. integration is coming up next

thx - i now conclude it depends on the equation:)
