Consider tetrahedron whose three coterminous edges are represented by axb, xč and cxa, where a = (2+ sin 0)i + (cos 0)j + (sin 20)k 2π 6 — sin (0+²)i +cos (0 + ²)i + sin(20 + 7) k 3 3 3 2π = sin sin (0-²)i +cos (0-3); + sin ( 20 - 47 ) k 3 3 Where 8 € (0,7). Let f(0) represent volume of tetrahedron, then (A) No. of solution of f(0) = is 3 (B) Maximum value of f(0) is 2 (C) 5 Σ1 (3) - 9 (D) No. of non-differentiable points of √f(0) is 1 कोरो को से दर्शाते है जहाँ
