Question

Determine all solutions of the given equation. Express your answer(s) using radian measure. (Select all that apply.)

Tan theta = -1

a. theta = 2pi(k), where k is any integer
b. theta = pi+2pi(k), where k is any integer
c. theta = 3pi/2 + 2pi(k), where k is any integer
d. theta = 3pi/4 + pi(k), where k is any integer
e. None of these

Answer 1

Tangent has a period of 2pie and so a is definitely correct, I would guess that b and c are also correct because they both have 2 pie in it.

Answer 2

It was just d.

Answer 3

oh well I was way off
