You're on a roll — Let's clarify Step 3. The original Left-Hand Side (LHS) expression is: LHS = (1)/(i + s')(1+s')^n - 1 In Step 2, we established that for this identity to hold, we assume s' = i. Step 3 is about substituting s' with i. This means we look for every instance of s' in the expression and replace it with i. Let's break down the LHS: • The main numerator of the entire fraction is 1. There is no s' in this part. So, it remains 1. • The main denominator is i + (s')/((1+s')^n - 1). • The first term in the main denominator is i. This is not s', so it remains i. • The second term in the main denominator is a fraction: (s')/((1+s')^n - 1). • The numerator of this smaller fraction is s'. This is where we substitute s' with i. So, it becomes i. • The denominator of this smaller fraction is (1+s')^n - 1. Here, we substitute s' with i. So, it becomes (1+i)^n - 1. Putting it all together after the substitution: The main numerator is 1. The main denominator becomes i + (i)/((1+i)^n - 1). So, the entire LHS after substitution in Step 3 is: LHS = (1)/(i + i)(1+i)^n - 1 The 1 in the main numerator is not an s', so it does not change to i. The i you are referring to is the s' that was in the numerator of the nested fraction within the denominator. Does that make more sense? Send me the next one 📸
