Question

3sin-¹x = sin-¹ (3x- 4x³)​

Answer 1

Answer:

Step-by-step explanation:

Answer 2

${3} \sin ^{ - 1} x = \sin {}^{ - 1} (3x - 4 {x}^{3} )$

Let x = Sin ∅

Then,

$\sin {}^{ - 1} = ∅$

We have,RHS,

$\sin {}^{ - 1} (3x - 4 {x}^{3} )$

$= \sin {}^{ - 1} (3 \sin ∅- 4 \sin∅)$

$= \sin {}^{ - 1} \sin \: 3∅</p><p>$

$= 3∅$

$= 3 \sin {}^{ - 1} x = LHS$
