Hello, I'm new here and this is my first post, but let me get right to the problem.

I have several functions to graph. Explanations are appreciated, I'm not looking to just get answers.

1.) y = tan (2 + ) + 1

2.) y = cot ( /2 - /2) - 2

3.) y = csc + 3

4.) y = sec ( /3 + ) - 1

Any help is appreciated. Thank you.
