1. The problem statement, all variables and given/known data
Simplify the following. Write all trigonometric
functions in terms of t.

2. Relevant equations

3. The attempt at a solution
I know that:
sec(t+2pi)=sec(t)

1+tan(t+3$$\pi$$)= 1+tan(t)

What about: csc(t-6$$\pi$$)??? Will it be equal to csc(t).
