Judge the parity of F (x) = 1 + SiNx − cos2x1 + SiNx

Judge the parity of F (x) = 1 + SiNx − cos2x1 + SiNx

From the analytic expression of the function, we can get SiNx ≠ - 1, X ≠ 2K π - π 2, K ∈ Z. obviously, the domain of definition of the function is not symmetric about the origin, so the function is not odd or even
