$(11.388,42.501)$

Note the Cartesian form cannot have the modulus negative so I assume the $-44$ should be $44$ .

To convert polar form $(r,theta)$ to rectangular form $(x,y)$ , we use the following transformations :

$x=rcostheta=44cos((5pi)/12)=11.388$ .

$y=rsintheta=44sin((5pi)/12)=42.501$ .

What is the Cartesian form of (-44,(5pi)/12))(-44,(5pi)/12))?
