for

x

, where

x \in R

.

x \in ⋃_{k \in Z} [{k π} \cup {\frac{π}{4} + 2 k π} \cup {\frac{3 π}{4} + 2 k π}]

x \in ⋃_{k \in Z} [{\frac{π}{4} + 2 k π} \cup {\frac{3 π}{4} + 2 k π}]

x \in ⋃_{k \in Z} [{\frac{π}{4} + k π} \cup {\frac{3 π}{4} + k π}]

x \in ⋃_{k \in Z} [{2 k π} \cup {\frac{π}{4} + k π} \cup {\frac{3 π}{4} + k π}]
