if the sum of first n terms of an A.P. is cn 2 ,then the sum of squares of these n terms is (A) n(4n 2 -1)c 2 /2 (B) n(4n 2 +1)c 2 /3 (C) n(4n 2 -1)c 2 /3 (D) n(4n 2 +1)c 2 /6
 
 
A be the first term and d be the difference of the AP sum of n terms is n(A + d(n-1)/2) = cn 2 simplifying we get the equation as (A-d/2) + nd/2 = cn now comparing coefficients in...

Sin 2π/7+sin4π/7+sin8π/7 . it`s numeric value
 
 
We seek S = sin (2π/7) + sin (4π/7) - sin (π/7) Let s = sin(π/7), c = cos(π/7) so s² + c² = 1. From cos(α + β) and sin(α + β) formulas come cos(2π/7) = c² - s² = 2c² - 1 sin(2π/7) = 2cs...
