i need more help in calculus !!
« on: June 06, 2006, 11:14:02 AM »
 :'( i have exams in a week, and i suck... i'm trying to cram 4 weeks worth of work...

anyway, i'm struggling with area under curve, only when the boundaries are the y-axis... i cant re-write the equation to suit the x-axis and work it out from there... thats just my lack of high-school knowledge i know... but these calculus books dont teach shit.

y=X^(1/2) , x=0, y=1, y=3

it's all too easy when the boundaries are the x-axis, but y just shits me... please help !!!

ivee sussed out you just substitute the y=3 or y=1, and get the values of x through algebra... but how do i re-make the equation into y= ???

damn this late night study is killing me  :-X

so i did it, but using unorthodox methods...

i got the area for the boundaries x=1 and x=9, (the area under the curve), then i subtracted it from the area of the square (luckily in this problem it was a strait line boundary), the remaining shizz is the area over the curve..

but i wont know how to do it for quadratics  :-\

it's mandatory, i only have 2 chances to pass this unit, if i fail 2 times i'm deemed too dumb to complete the course..

well if i was in America, i'd be considered an engineer... but because i'm studying in australia, i'm classified as a Surveyor... basically i measure shit, boundaries, movement of dams, mapping and planning... shit like that... i'm also doing a double degree, so i'm doing surveying & commerce entrepreneurship...

theres a heap of math, but at the end of the day, i'll be out-side most the time, there wont be much office time, thats the big seller..
