QUESTION: 18

If cos-1p + cos-1q+cos-1r = π, then p2 + q2 + r2 + 2pqr is equal to

Solution:

Let cos-1 p = α, cos-1 q = β and cos-1 r = γ
⇒ cosα = p, cosβ = q and cosγ = r
From question, α + β + γ = π
∴ cos (α + β) = cos (π - γ) Squaring, we get p2q2 + r2 + 2pqr = 1 - p2 - q2 + p2q2
or, p2 + q2 + r2 + 2pqr = 1
