Q1 of 303 Page 4

Evaluate each of the following:
sin^–1(sin3)

sin^–1(sin x) = x

Provided x ϵ ≈ [–1.57,1.57]

And in our equation x is 3 which does not lie in the above range.

We know sin[π – x] = sin[x]

∴ sin(π – 3) = sin(3)

Also π–3 belongs in

∴ sin^–1(sin3) = π–3

Evaluate each of the following:

sin^–1(sin4)

Evaluate each of the following:

sin^–1 (sin12)

Evaluate each of the following:sin–1(sin3)
