**k**(**k**+1)(2k+1)/6 must be divisible by 100 means**k**(**k**+1)(2k+1) divisible by 600 which is 5x5x2x2x2x3 2k+1 is odd, and only one of**k**or**k**+1 can be even so you need**k**or**k**+1 divisible by 8 one of**k**,**k**+1, and 2k+1 will always be divisible...4 Answers · Science & Mathematics · 18/12/2013

(

**k**-1)x^2+2x-(**k**-3)=0 suppose**k**-1=a and**k**-3=b so,a-b=**k**-1-**k**+3=2 so the equation becomes ax^2+(a-b)x-b=0 => ax^2+ax-bx-b=0 =>ax(x+1)-b(x+1)=0 =>(ax-b)(x-1)=0 x=-1 or x=b/a=(**k**-3)/(**k**-1)5 Answers · Science & Mathematics · 31/01/2011

**k**(x) = 2 sin (x+π) / (sin (x+π) - 3) = 2 (- sin x) / (- sin x - 3) = 2 sin x / (sin x + 3) = [2 (sin x + 3) - 6] / (sin x + 3) = 2 - 6 / (sin x + 3) So for**k**^-1(x) we get x = 2 - 6 / (sin**k**^-1(x) + 3) => 6 / (sin**k**^-1(x) + 3) = 2 - x =>...1 Answers · Science & Mathematics · 16/12/2013
