Is this correct? Solve the equation on the interval of \( 0\geq \theta < 2\pi \)
\( 2cos \theta + 3 = 2 \)
\( 2 cos \theta = 2-3 \)
\( 2 cos \theta = -1 \)
\( \frac{2 cos \theta}{2} = \frac{-1}{2} \)
\( cos \theta = \frac{-1}{2} \)
This was on my midterm and I made an A on it but this one I got wrong but this looks correct? What did I do wrong?

wait how many answers did you provide? there are two answers.

One sec it should be \(\huge 0\leq \theta < 2\pi \)
