Find all exact solutions of the equation tan(x)=-1 in the interval [0,2π]

Question

I got the answer of -π/4 +- πn and -3π/4 +- πn. Is this the correct answer? I'm asking because I think it's right, but I only have a limited number of tries to submit it.

Answer 1

-pi/4 is not in [0,2pi]...fix that by adding 2pi.

 

the two correct answers correspond to angles having DEGREE measure 135 and 315.
