Which of the following statements is NOT true?

W) cos(-\(x\)) = cos(\(x\)) [cosine of negative x equals cosine of x]

X) tan(-\(x\)) = tan(\(x\)) [fangent of negative x equals tangent of x]

Y) The amplitude of \(y\) = -2 cos(\(\delta\)) is equal to 2

Z) The range of \(y\) = -5 sin(\(\delta\)) is [-5, 5] [the closed interval from negative 5 to 5]
X) tan(-\(x\)) = tan(\(x\))
