mmm....i thot that so aswell but they might just be loading as u scrolll down just wait for a while nd then check againSome pages are blocked...
v = 4t - 1/16*t^3
So you got that answer or I should explain it to you?
thnk u so muchv = 4t - 1/16*t^3
s = 2*t^2 - 1/64*t^4 + c
we know that when t=0, s=0 as well:
0 = 0 - 0 + c
c = 0
s = 2*t^2 - 1/64*t^4
Distance PQ is 64m, so we just have to find the value of t for which s=64:
64 = 2*t^2 - 1/64*t^4
t = +/-8
t = 8 (reject negative)
ii)
a = 4 - 3/16*t^2
a>0
4 - 3/16*t^2 > 0
and you do the rest
mmm explain ??
That integration question.mmm explain ??
Plus the thing I was talking about 90 is odd, I know it did not made any sense, I meant to say, ignore the zero and see the previous number(s) is/are even or odd. In case of 90, "9" is a odd number. In case of 180, "18" is a odd number.mmm explain ??
yes can u plzzzzzzzzzzz explain it???
To find the shaded area over here using integration is subtracting the integrals.
writing =
....thnk u
part ii) and iii) are easy and straightforward
If you use cos you will get a values which isn't the acute angle then you have to 180-(cos-1(...)) we use sin for angle between line and plan
For almost 10 years, the site XtremePapers has been trying very hard to serve its users.
