ye i get what u mean that by subbing a value > 0, the function is increasing as the gradient is > 0. but i was askin how you know its for all values of x, since there r may be turnin points after x = 0 i suppose the bok did lim x-> infinity or somefin.....

^ oops makes sense. now

huh^ wtf. your not answerin the question now,

im not trying to find the turning points. the question just asks to "show that this curve is increasing for all x=>0" the question im askin is how does the first deriviative prove that for all values for x it is increasing?

^lol wtf. doesnt make sense

1.how do you prove a function is increasing for all x greater than or equal to 0. let f(x) = sqr(x) the solution just finds the deriviative, but how does it conclude its increasing for all values of x. 2. whats the difference between a horizontal point of inflexion and a point of inflexion...

ok i sorta get the idea now. So the reponse will be based around your own personal response/reading. but im still sorta lost of what the your own reading is, like what aspects of the texts do u have to discuss? themes, charactres, plot and the way its emphasised and how the modern context...

hi, im so confused about this module, i do wuthering heights, but i think people who do other texts can help me. Well firstly, i understand for this module that your suppose to do different readings like psychoanalytical, feminist etc... But my teacher also said you have to do personal...

8! x 2! from the way i interpret ur question? theres 8 couples, so 16 people rite? each couple is opposite to another so theres 2 people facing another 2 people rite?

lol. u mind doing it for me? idk if my answer is rite. i got 2/3 units^2

hi, can someone solve this question? Find the area by the curve y=x^2 and the lines x=o, y=1.

Hi guys, im having stuck on a few conics questions from the terrylee book. The answers dont explain it properly, or atleast it doesnt make sense to me. 1. The normal at an end P(x1,y1) of the latus rectum of the ellipse (x^2)/(a^2)+(y^2)/(b^2) = 1 meets the y-axis in M, and Pn is the abscissa...

Hi, having trouble with a few questions regarding the inverse topic. 1. State the domain and range of each of the following functions: a) y=InverseTan (Sqrt (1-x^2)) b) y=InverseCos (Sqrt (1/4-x^2)) c) y= xInverseSin (x^2) I could get the domain, however the range is weird, answers for...

okz coolz, ye so guess ill spend my time on 3u/4u. thanks guys

Im currently doing 4 unit, and my half yearlies are coming up in lil under 2 weeks. Wandering if you guys study for ur 2u exams at all? Im stuck in a dilema in deciding if i should or should not, and if so how much time i should dedicate towards it, just as a back up. On the otherhand do i rly...

Hi, can anyone give me an outline of the two experiments relating to galvanic cells for electrochemistry topic (prod. of material). • perform a first-hand investigation to identify the conditions under which a galvanic cell is produced • perform a first-hand investigation and gather...

1. firstly the stationary point has the nature maxima/minima TP or the point of inflexion rite? 2. a stationary point is a point of inflexion when from the first deriviative, using the table of values the signs are both + or both -. rite? 3.the points of inflexion can also be determined by...

the x intercepts was the problem.......the textbook also didnt giv answers... k fk it.

fk,, 2u's bein pissin me off more than 4u.

use the quadratic formula: [-b (+or-) squareroot (b^2-4ac)]/2a
