Maybe i can take a pic but can't do it right now, tomorow morning ?is there any way at all that you could help me?
all right one confusion..if i get -5x+3y+4z=2 as the equation of plane and the marking scheme says 5x-3y-4z=-2. will my answer be considered wrong?Maybe i can take a pic but can't do it right now, tomorow morning ?
No, its absolutely correct!all right one confusion..if i get -5x+3y+4z=2 as the equation of plane and the marking scheme says 5x-3y-4z=-2. will my answer be considered wrong?
what?! is that a rule?Got it for the integral of 1/(a square+x square) the integral Wud b 1/a tan inverse of (x/a) +c
[ln (1+x^2)]/2xHow Wud u integrate 1/(1+X^2) ?

Q. 8 (ii) from the paper. For some reason I'm getting ln25 + ln8. Please help!

please explain question 10 part (iii) please
thanks !I didn't make these, all thanks goes to the members here
nope,380 is greater than 360 so is incorrect.wth? don't you just divide it by 2 after getting 380.8?
[ln (1+x^2)]/2x
Its a rule .. integration of 1/x is lnx and in this case you just go back and divide by the differenciation of the inner term hence the division by 2x
The tangent of line of a point on the curve is has dy/dx. Same as the differential of that curve on that pointhttp://www.xtremepapers.com/papers/...S Level/Mathematics (9709)/9709_s11_qp_32.pdf Q 10 part iii how to do it !! i know its easy but i dont get it
