You're on a roll — Let's explain the Left Hand Side (LHS) of the expression shown in the image: LHS = (1)/(i) + (1)/((1+i)^n - 1) Step 1: Understand the first term, (1)/(i). • This term represents the present value of a perpetuity. A perpetuity is a series of equal payments that continue indefinitely. If you receive 1 unit of money at the end of each period forever, and the interest rate per period is i, then the present value of all those future payments is (1)/(i). Step 2: Understand the second term, (1)/((1+i)^n - 1). • This term is related to the future value of an ordinary annuity. The formula for the future value of an ordinary annuity of 1 unit of money per period for n periods at an interest rate i is s_n|i = ((1+i)^n - 1)/(i). • Therefore, the term (1)/((1+i)^n - 1) can be written as (1)/(i · s_n)|i. It represents the reciprocal of the future value of an annuity of 1 per period, multiplied by i. This is not a standard standalone financial factor. Step 3: Combine the two terms on the LHS. To add the two fractions, we find a common denominator, which is i((1+i)^n - 1). LHS = (1)/(i) + (1)/((1+i)^n - 1) Multiply the numerator and denominator of the first term by ((1+i)^n - 1): (1 · ((1+i)^n - 1))/(i((1+i)^n - 1)) = ((1+i)^n - 1)/(i((1+i)^n - 1)) Multiply the numerator and denominator of the second term by i: (1 · i)/(i((1+i)^n - 1)) = (i)/(i((1+i)^n - 1)) Now, add the two fractions: LHS = ((1+i)^n - 1)/(i((1+i)^n - 1)) + (i)/(i((1+i)^n - 1)) LHS = ((1+i)^n - 1 + i)/(i((1+i)^n - 1)) This is the simplified form of the Left Hand Side.
