Two points in a plane have polar coordinates P1(2.500m, pie/6) and P2(3.800m, 2pie/3) .
Determine their Cartesian coordinates and the distance between them in the Cartesian coordinate system. Round the distance to a nearest centimeter.
Ax=Acosθdist((x, y), (a, b)) = √(x - a)² + (y - b)²
The Attempt at a Solution[/B]
I converted the points to cartesian and got (2.165m,1.250m) and (-1.900m ,3.290m)
I'm confused because when I try to find the distance between the points, I use the distance formula and get 4.54meters as my answer. The correct answer should be 5.27m
What am I doing wrong?
Thanks in advance
