y=(f + 2)/f
y=1 + 2/f
y -1=2/f
f = 2/(y-1)

If the solution for θ of cospθ + cosqθ = 0, p > 0, q > 0 are in A.P., then the numerically smallest common difference of A.P. is
Detailed Solution for TS EAMCET Mock Test - 4 - Question 21

Given cospθ = - cosqθ = cos (π + qθ)
⇒ pθ = 2nπ  (π + qθ), n ∈ I
⇒ θ = (2n + 1)π/p - q or (2n - 1)π/p + q , n ∈ I
Angle θ = (2n + 1)π p - q given us an AP with common
difference 2π/p - q and θ = (2n - 1)π/p + q gives also an AP with common difference 2π/p + q
Then, certainly, 2π/p + q < | 2π/p - q |
∴ The smallest common difference is 2π/p + q
