1) Use the set-roster notation to indicate the elements in each of the following sets. a) \( \mathbf { i } \cdot \mathbf { S } = \{ \mathbf { n } \in \mathbf { Z } | \mathbf { n } = ( - 1 ) \mathbf { k } , \text { for some integer } \mathbf { k } \} \) ii. \( \mathrm { T } = \left\{ \mathrm { m } \in \mathrm { Z } | \mathrm { m } = 1 + ( - 1 ) ^ { \mathrm { i } } , \text { for some integer } \mathrm { I } \right. \) ii. \( U = \{ r \in Z | 2 \leq r \leq - 2 \} \) iv. \( \mathrm { V } = \{ \mathrm { s } \in \mathbf { Z } | \mathrm { s } > 2 \text { or } \mathrm { s } < 3 \) \( \mathbf { v } . \mathbf { W } = \{ \mathbf { t } \in \mathbf { Z } | 1 < \mathbf { t } < - 3 \} \) vi. \( \mathrm { X } = \{ \mathrm { u } \in \mathbf { Z } | \mathrm { u } \leq 4 \text { or } \mathrm { u } \geq 1 \} \)
