Components of the vector between origin and polar coordinates #(1,(5pi)/8)# are #-0.3827# and #0.9239#.

Explanation:

Components of the vector between origin and polar coordinates #(r,theta)# are #rcosheta# and #rsintheta#.

Hence components of the vector between origin and polar coordinates #(1,(5pi)/8)# are

#1xxcos((5pi)/8)# and #1xxsin((5pi)/8)# or

#cos((5pi)/8)# and #sin((5pi)/8)# or

#-0.3827# and #0.9239#
