(L-1)Number of integral values of $x$ satisfying $3 x^{2} + 8 x < 2 sin^{- 1} sin 4 - cos^{- 1} cos 4$ is

Answer:

Solution:

$3 x^{2} + 8 x < 2 sin^{- 1} sin 4 - cos^{- 1} cos 4$

$3 x^{2} + 8 x < 2 (π - 4) - (2 π - 4)$

$< 2 π - 8 - 2 π + 4$

$< - 4$

$\Rightarrow 3 x^{2} + 8 x + 4 < 0 ha so n eso l u t i o n$
