WebExample 3.6.1. Use mathematical induction to show proposition P(n) : 1 + 2 + 3 + ⋯ + n = n(n + 1) 2 for all integers n ≥ 1. Proof. We can use the summation notation (also called the sigma notation) to abbreviate a sum. For example, the sum in the last example can be written as. n ∑ i = 1i. solar dealers in bangaloreWeb``STRAIGHT'' INDUCTION is an occasionally useful proof technique.
