You can put this solution on YOUR website! 215. Give the rectangular coordinates: (2, 45°)
Answer Choices:
A)(√5, √5) C)(√3, √3)
B)(√2, √2) D)(2,2)
-----------
--> (sqrt(2),sqrt(2))
------------------
216. Give the rectangular coordinates: (-6, -150°).
Answer Choices:
A)(3√3, 3) C)(3, 3√3)
B)(-3√3, 3) D)(-3, 3√3)
Do it like 215 above. You sure that's -6 ?
=======================
217. Give the polar coordinates: (-2, 2).
Anser Choices:
A)(2√2, 135°) C)(135, 2√2°)
B)(2√2, 135) D)(135, 2√2)
----------
angle = arctan(y/x) = arctan(-1) = 135 degs
-----
--> (2sqrt(2),135)
=======================
