In a `Delta ABC, c cos^2 A/2+a cos^2C/2=(3b)/(2)` then show a,b,c are in A.P

Text Solution

AI Generated Solution

To show that \( a, b, c \) are in Arithmetic Progression (A.P.), we start with the given equation: \[ c \cos^2 \frac{A}{2} + a \cos^2 \frac{C}{2} = \frac{3b}{2} \] ### Step 1: Use the half-angle formula We know from trigonometric identities that: ...
