Step 1
Polar coordinates of two points are r 1 = 10 , θ 1 = 17 π 12 =
255 0 and r 2 = 4 , θ 2 = 15 π 8 = 337.5 0
Cartesian coordinate of 1st point is x 1 = r 1 cos θ 1 or
x 1 = 10 cos 255 - 2.588 and y 1 = r 1 sin θ 1 =
y 1 = 10 sin 255 - 9.659 ( - 2.588 , - 9.659 )
Cartesian coordinate of 2nd point is x 2 = r 2 cos θ 2 or
x 2 = 4 cos 337.5 3.696 and y 2 = r 2 sin θ 2 =
y 2 = 4 sin 337.5 - 1.53 ( 3.696 , - 1.531 )
Distance between two points is
D = ( x 1 x 2 ) 2 + ( y 1 y 2 ) 2 =
D = ( - 2.588 3.696 ) 2 + ( - 9.659 + 1.531 ) 2
D = 10.27 unit
