# How do you express the complex number in trigonometric form  2(cos 0° + i sin 0°)?

I am not sure if I got it right. Your number is in trigonometric form so maybe you want to change it into standard form $a + b i$...?
cos0°=1
sin0°=0
so your complex number becomes: $z = 2 \left(1 + i \cdot 0\right) = 2 + i 0 = 2$ which is a pure Real.
