Need solution for RD Sharma Maths Class 12 Chapter 3 Inverse Trigonometric Functions Excercise Fill in the Blanks Question 15

Answers (1)

Answer:

$-1$

Hint:

You must know the rules of inverse trigonometric function.

Given:

$\sin^{-1}x+\sin^{-1}y+\sin^{-1}z=\frac{-3\pi}{2}$

Solution:

$\sin^{-1}x+\sin^{-1}y+\sin^{-1}z=\frac{-3\pi}{2}$

$\because \frac{-\pi}{2}< \sin^{-1}x\leq \frac{\pi}{2}$

$\because \sin^{-1}x=\frac{-\pi}{2},\sin^{-1}y=\frac{-\pi}{2},\sin^{-1}z=\frac{-\pi}{2}$

$\because x=y=z=-1$

$\because xyz=-1$
