− sin ⁡ ( π 2 + θ ) sec ⁡ ( 5 π 2 + θ ) + cot ⁡ ( θ − 7 π 2 ) csc ⁡ ( θ + 2 π ) = 3 \dfrac{-\sin\left(\dfrac\pi2 + \theta\right) \sec \left( \dfrac{5\pi}2 +\theta \right) + \cot\left( \theta - \dfrac{7\pi}2 \right) }{\csc(\theta + 2\pi)} = 3

Solve the equation and find the value(s) of θ \theta in radian measures for 0 ≤ θ ≤ 2 π 0\leq \theta \leq 2\pi .
