Pls pls help it's urgent. Due in another few minutes!! which statement is true?
1. y=csc x and y=sec x intersect at y = 1.
2. the period of y =tan x is doubled the period of y=csc x.
3. the zeros of y= tan x and y= cos x are the same.
4. the local maximum points of y = sec x is the same as the absolute minimum points of y = sin x.
5. None of the above are true.
