" 3.If "x in R" and "b

If x in R and b

Let a=min {x^2+2x+3, x in R} and b=lim_(theta->0)(1-costheta)/(theta^2) then the value of sum_(r=0)^n a^r*b^(n-r) is :

Let a=min {x^2+2x+3, x in R} and b=lim_(theta->0)(1-costheta)/(theta^2) then the value of sum_(r=0)^n a^r*b^(n-r) is :

Given : A = {x : 11x - 5 gt 7x + 3, x in R} and B = {x : 18x - 9 ge 12x., x in R} .

Let a=min{ x^2+2x+3, x in R } and b=lim_(thetararr0)(1-costheta)/(theta^2) . Then the value of sum_(r=0)^na^rb^(n-r)

If A = { (x,y) : y = sin x, x in R } and B = { (x,y) : y = cos x, x in R} then A cap B contains

If A= {(x,y) : y = e^(x), x in R } and B = { (x,y) : y = e^(-x), x in R } then n (A cap B ) is
