Express each of the following complex numbers in Cartesian form, i.e., \(x+iy\), where \(x\) and \(y\) are real numbers.

\(3\left( \cos \frac{\pi}{6} + i \sin \frac{\pi}{6} \right)\)

\(7\left( -\cos \frac{\pi}{4} + i \sin \frac{\pi}{4} \right)\)

\(2\left( \cos \frac{\pi}{3} + i \sin \frac{\pi}{4} \right)\)
