Trigonometric form of $12e^(((5pi)/2i)$ is $12cos((5pi)/12)+i12sin((5pi)/2)$

The trigonometric form of a complex number $z=re^(itheta)$ is

$z=rcostheta+irsintheta$

Hence trigonometric form of $12e^(((5pi)/2i)$ is

$12cos((5pi)/12)+i12sin((5pi)/2)$

What is the trigonometric form of 12 e^( ( 5 pi)/2 i ) 12 e^( ( 5 pi)/2 i ) ?
