My answer to this is [MATH](4, π/6)[/MATH]. But a calculator said that [MATH](−4, 7π/6)[/MATH] is also an answer. Are both correct answers?
There is no hard and fast rule. But it is my preference that yours is the one that I would expect if I were your lecturer.My answer to this is [MATH](4, π/6)[/MATH]. But a calculator said that [MATH](−4, 7π/6)[/MATH] is also an answer. Are both correct answers?
This is the most important question: "What does your textbook/instructor say about polar coordinates?"I saw this explanation in an Algebra II book. (I don't know the book name because I just saw the polar coordinates section).
It gave two answers. I don't understand why those two can be both polar coordinates of (-1,1).
