Answer:
Odd, Even
Step-by-step explanation:
A function is said to be an Even function if it follows f(-x) = f(x).
A function is said to be an Odd function if it follows f(-x) = -f(x).
It means we can plug -x in place of x and check if it comes out to be f(x) or -f(x) i.e. y or -y?
Given y = sin³x/cos³x and y = 1/sec³x
Hence, first function is Odd, second function is Even.
