a.
To show that
Given information:
The geometric series with first term
Proof:
Multiply both sides of the equation
Hence, the proof.
b.
To use the part (a) to show that
Given information:
The geometric series with first term
Calculation:
From part (a), the relation is
Subtract
Therefore,
c.
To use the part (b) to show that
Given information:
The geometric series with first term
Calculation:
From part (b), the relation is
Solve this equation for
Thus,
Now, further simplify to get
Therefore,
