Hello, can someone explain me this, dont know what i need to do, how i can solve it?

Please help me

a) prove that if ¨f¨is periodic with period p, then 1/f is also periodic with period p.

b) prove that cosecant and secant each have period 2π.

We know that

A function f is said to be periodic with period P (P being a nonzero constant) if we have

f(x) = f(x+P)

for all values of x. If there exists a least positive constant P with this property, it is called the prime period. A function with period P will repeat on intervals of length P, and these intervals are referred to as periods.

Now i think that would answer all your queries.
