Prove that : Find the sum of the infinite series 1+(2)/(3).(1)/(2)+(2.5)/(3.6)((1)/(2))^(2)+(2.5.8)/(3.6.9)((1)/(2))^(3)+......oo

Let A={-1,1,-2,2},B={3,4,5,6} and f: A rarr B be the mapping defined by f={(1,6),(-1,4),(2,3),(-2,5)} . Prove that, f is a bijective mapping

Show that 1 + 2/3.1/2 + (2.5)/(3.6) (1/2)^2 + (2.5.8)/(3.6.9) (1/2)^3 + ….. = root(3)4
