Question

sin⁻¹(sin 7π/6) is.......,Select Proper option from the given options.
(a) π/6
(b) 5π/6
(c) -π/6
(d) 7π/6

Answer 1

ans is option -π/6 bcoj in third coordinate sin value is negetive

Answer 2

Answer:

-π/6

Step-by-step explanation:

We have to find the value of the given function Sin⁻¹(Sin 7π/6).

Let us assume that, y= Sin⁻¹(Sin 7π/6)

⇒ Sin y = Sin(7π/6) = Sin (π + π/6) = -Sin π/6 =-1/2= Sin (-π/6)

Here, 7π/6 lies in the third quadrant where Sin value is negative.

Therefore, y must be equal to -π/6. (Answer)

{Since Sin (-x) =- Sin x.}
