Mar 22, 2017

The Range is #[0,2]={ x in RR : 0 le x le 2.}#

Explanation:

Observe that, #AA x in RR, -1 le sin x le 1.#

Adding #1# throughout the inequality, we have,

# AA x in RR, -1+1 le sinx +1 le 1+1, i.e., #

# AA x in RR, 0 le F(x) le 2.#

Hence, the Range is #[0,2]={ x in RR : 0 le x le 2.}#
