To prove that if \( a, b, c \) are in Arithmetic Progression (AP), then \( \frac{1}{bc}, \frac{1}{ca}, \frac{1}{ab} \) are also in AP, we can follow these steps: ### Step 1: Understand the condition for AP If \( a, b, c \) are in AP, then by definition: \[ b - a = c - b \] This can be rearranged to: ...
