I was wondering if it was possible to multiple 2 complex numbers in trigonometric form.

For example if I had the following complex numbers in expressed in polar form.

z1 = 6 < 35

z2 = 2 < 25

I convert these complex numbers into trigonometric form and I get:-

z1 = 6 (cos(35) + sin(35)i)

z2 = 2 (cos(25) + sin(25)i)

My question is can I multiply the two complex trigonmetric numbers and a valid result?

I can multiply them in polar form which gives me 12 < 60 but I'm struggling with the trigonometric form.

Thank you.
