Let f(n)(theta) = ("cos"(theta)/(2)+ cos...

Let `f_(n)(theta) = ("cos"(theta)/(2)+ cos 2 theta + "cos" (7 theta)/(2)+....+ cos (3n - 2) (theta)/(2))/("sin"(theta)/(2) + sin 2 theta + "sin" (7 theta)/(2) +....+sin (3n - 2) (theta)/(2))`.
Then match the entries of column-I with their corresponding values given in column-II.
`{:(,"Column-I",,"Column-II"),((A),f_(3) ((3pi)/(16)),(p),2 - sqrt(3)),((B),f_(5) ((pi)/(28)),(q),sqrt(3 + 2sqrt(2))),((C),f_(7) ((pi)/(60)),(r),sqrt(2) - 1),(,,(s),2 + sqrt(3)):}`
