Hello I need help with this q Suppose that Tn= ar^(n-1) is a gp with a limiting sum Find the ratio if the sum of all terms except the first equals 5 times the first term I started with Sn - T1=5T(1) T(1)= a Sn= 6a But dont know where to go from there...

Thanks again integrand! Sent from my LG-D855 using Tapatalk

Prove that the sum Sn of the first n terms is always 7 less than the ( n +1)th term The sum Sn of the first n terms : 7(2^n-1) help pwease thank you

Ooooooooh dam i suk, thank you for help :) Sent from my LG-D855 using Tapatalk

yea 9/8 was the answer thanks guys

By using the same axes and scales , sketch the curves y=cosx and y=cos2x for 0<=x<=1/2pi FOr this interval of values of x, find the maximum distance between the two curves measured parallel to the y-axis Help on how to approach this question after sketching the graphs THanks

ye doing 2u, but i needed to roots to find the area between two curves lol

Oh i see, this is still a bit confusing but i just divide by the factors of the constant term to find a root right?

i) Show that the curves y=x^2+4 and y=x^3 intersect at the point ( 2, 8) HOw do i factorise x^3-x^2-4=0 THanks

Sketch the curve y=(x-1)(x+1)(x-3) and shade the region enclosed by the curve, the x-axis and the ordinates x=0 and x=2. Find the total area of the region ANS: 7/2 units ^2 i keep getting a negative value for the postive area of the curve
