Find the product of z1 and z2, where z1 = 5(cos 60° + i sin 60°) and z2 = 7(cos 210° + i sin 210°)

Write in a + bi form

The function which is made up of the real numbers, as well as imaginary numbers, are called complex numbers these numbers are represented by a +ib form where the first part is the real part and the second part is the imaginary form.

The product of the two complex numbers will be done as:-

[tex]z_1z_2=r_1r_2Cos (\theta_1+\theta_2)+iSin(\theta_1+\theta_2)[/tex]

[tex]z_1z_2= 5\times 7[Cos(60+210)+iSin(60+210)][/tex]

[tex]z_1z_2=35[(Cos270)+iSin(270)][/tex]

Therefore the product of the two complex numbers is 35[Cos270 + i Sin(270)].
