Problem
Convert the given point from rectangular form to polar form. \[ (6,-13) \] \( \left(14.3,[?]^{\circ}\right) \) Round your answer to the nearest tenth. Givè your answer in degrees.
Solution
Step 1 ：\(r = \sqrt{6^2 + (-13)^2} \)
Step 2 ：\(\theta = \arctan\left(-\frac{13}{6}\right)\)
Step 3 ：\( \left( 14.3, -65.4^{\circ} \right) \)
