Question
Rectangular Coordinates to Polar Coordinates Convert the rectangular coordinates to polar coordinates with $r>0$ and$0 \leq \theta<2 \pi$. $$(1,-2)$$
Step 1
The formula for $r$ in polar coordinates is $r=\sqrt{x^2+y^2}$. Here, $x=1$ and $y=-2$. So, we substitute these values into the formula: $$ r=\sqrt{1^2+(-2)^2}=\sqrt{1+4}=\sqrt{5} $$ Show more…
