The function y = 2Sin (2x − π) 6) The monotone decreasing interval of is______ .
Let 2x − π
6∈[π
2+2kπ,3π
2 + 2K π], X ∈ [K π + π] can be obtained
3, kπ+5π
6](k∈Z)
The function y = 2Sin (2x − π)
6) The monotone decreasing interval is [K π + π]
3, kπ+5π
6](k∈Z)
So the answer is: [K π + π
3, kπ+5π
6](k∈Z)
