If the pth and qth terms of an AP be a and b respectively, show that the sum of the first (p+q) terms of the AP is (p+q)/2{a+b+(a-b/p-q)}
 
 
Hello Student, Now its obvious. Substitute the values to get the answer. Thanks & Regards Arun Kumar Btech, IIT Delhi Askiitians Faculty

X*4+ax*3++bx*2+cx+d be a polynomial equation with real cofficients and real zeroes.if |f(i)|=1.find a+b+c+d.i=root of -1
 
 
f(i)=1-ai-b-ci+d=1 1-b-d=real part=1 -i(a+c)=complex part =0 b+d=0 a+c=0 a+b+c+d=0 sher mohammad b.tech, iit delhi

If p,q,r,s are the real roots of the polynomial, then f(i) = (i-p)(i-q)(i-r)(i-s) and hence |f(i)| = (1+p^2)(1+q^2)(1+r^2)(1+s^2) >=1. But |f(i)| = 1 and hence we must have p=q=r=s=0 i.e....

solution: a= min (x^2+ 4x +5) ( using dy/dx= 0 at critical points) y= x^2+ 4x +5 ; dy/dx = 2x+4 = 0 so x = -2 d 2 y/dx 2 = 2(-2) + 4 = 1 so minimum.. so a = 1 b = lim y --> 0 = (1- cos...

he value of k if the lines (2x+3y+4)+k(6x-y+12)=0 are parallel to y- axis
 
 
The eq. can be written as (2+6k)x+(3-k)y+(4+12k) =0 slope of eq. = -(2+6k)/(3-k) since it is parallel to y axis so slope of the eq. is infinity. Hence 3-k=0 so k=3 Thanks & Regards...
