In the angles

A,B

and

C

of a triangular are in the arithmetic progression and if

a,b

and

c

denotes the lengths of the sides opposite to

A,B

and

C

respectively, then the value of the expression

\frac{a}{c}\sin \;2C + \frac{c}{a}\sin \;2A

View answer and explanation

Correct option: D

\sqrt 3

Option D (

\sqrt{3}

) is correct because the expression simplifies to 2sinB, and since B = 60 degrees, the value is

\sqrt{3}
