Question 1076717: Which of the following are equivalent?
i.
π/2 + kπ, for k an integer.
ii.
−π/2+ kπ, for k an integer.
I am not sure where to start with this. Does it have something to do with the cofunction identities?

Which of the following are equivalent?
i.
pi/2 + kpi;, for k an integer.
ii.
-pi/2+ kpi, for k an integer.
===================
There are only 2 given.
And, they're equivalent.
---
pi/2 + kpi --> for k = -1 to 3, -pi/2, pi/2, 3pi/2, 5pi/2, 7pi/2
---
-pi/2 + kpi --> for k = 0 to 3, -pi/2, pi/2, 3pi/2, 5pi/2
