 Question 631539: Please use a calculator to change the rectangular coordinates (-2.5,7) to polar form. Round r and θ to 3 decimal places and let -180° < θ < 180°. Thanks!Answer by Alan3354(30983)   (Show Source): You can put this solution on YOUR website!Please use a calculator to change the rectangular coordinates (-2.5,7) to polar form. Round r and θ to 3 decimal places and let -180° < θ < 180°. ============================ Do it like this one: ---------- Please use a calculator to change -0.135 + 1.67i to polar form. Round r and θ to 3 decimal places and let –л < θ ≤ л. --------------- r =~ 1.657 ---- Angle = atan(1.67/-0.135) Angle =~ 94.622 degs
