Ghost Of Highbury:
(1-x/4) ( 12x+60x^2+160x^3+240x^4.....)
(....160x^3 + 240x^4)(1-x/4)
160x^3 - (160x^4/4) + 240x^4 = ....240x^4 - 40x^4.... = 200x^4
hence, 200

Thanks agen guys ;D
cooldude:
now the second q-->
in the first part we found that the derivate is 3xe^3x
the simplest explanation i can give is that the integral of xe^3x will be 1/3 of the expression given to differentiate in part i is cuz the derivate we found in the second part is 3 times the integrand in part ii, thus since differentiation is the opposite of integration we divide it by 3 as the derivate we got in part i is 3 times the integrand in part ii, the other way i knw to find the integral is integration by parts but im not sure whether u add maths guys knw that as ive never done add maths myself so i have no idea what the syll is :D , neway it wont make a diff since the q says hence, so just try and understand what i said or wait until sum1 can give a better explanation

There you go.
jellybeans:
HIIII, um, i need help with Q12ii) pleaseeee :)
Thanks :D
i knw you integrate the velocity to get the displacement but what values do you sub in? :o
