explanation please...thank you much

oobleck · Answer

really?
2tanx sinx + 2tanx = 0
2tanx (sinx + 1) = 0
tanx = 0
sinx = -1
You should be able to take it from there.

and when posting a question, don't bother with things like
Give the exact solution, including "pi" for π. For any unused answer boxes, enter DNE in all capital letters.
Instructions for input format are for you -- they have nothing to do with solving the problem.
