Given complex numbers

a = 3 (\cos \frac{π}{3} + i \sin \frac{π}{3}), b = \sqrt{2} (\cos \frac{2 π}{3} + i \sin \frac{2 π}{3})

find the product

a b

.

- 3 \sqrt{2}

3 \sqrt{2} (\cos \frac{π}{2} + i \sin \frac{π}{2})

3 \sqrt{2} (\cos \frac{π}{2} - i \sin \frac{π}{2})

- 3 \sqrt{2} (\cos \frac{π}{2} + i \sin \frac{π}{2})
