4. The electric field of an electromagnetic wave $\vec{E} = \hat{a}_x E_0 \cos \left[ 2 \times 10^8 \pi \left( t - \frac{z}{c} \right) + \theta \right]$ is the sum of $\vec{E}_1 = \hat{a}_x 6 \sin \left[ 10^8 \pi \left( t - \frac{z}{c} \right) + \frac{\pi}{6} \right] \cos \left[ 10^8 \pi \left( t - \frac{z}{c} \right) + \frac{\pi}{6} \right]$ and $\vec{E}_2 = \hat{a}_x 4 \cos \left[ 2 \times 10^8 \pi \left( t - \frac{z}{c} \right) - \frac{\pi}{3} \right].$ Find $E_0$ and $\theta$.
