In the following functions, the even function which is a decreasing function in (0, π / 2) and whose minimum period is π is? A.y=tanx B.y=sinx C.y=cos3x D.y=|cosx|

In the following functions, the even function which is a decreasing function in (0, π / 2) and whose minimum period is π is? A.y=tanx B.y=sinx C.y=cos3x D.y=|cosx|

A: Odd function, f (- x) = Tan (- x) = - TaNx = - f (x)
B: The period of odd function 2pi is the same as above
C. Even function. Period 2pi / 3
The correct answer is the image of the absolute value of D. cosx, which is to flip all the images below the x-axis of the cosx image to the top of the x-axis
