Question
The polar equation of 
is
Hint:
The term "polar coordinate system" refers to a two-dimensional coordinate system where each point's location on a plane is determined by its distance from a reference point and its angle with respect to a reference direction. Here we have to find the polar equation of .
The correct answer is:
Using the formula, we may generate an endless number of polar coordinates for a single coordinate point.
(r, +2n) or (-r, +(2n+1)) are possible formulas, where n is an integer.
If measured in the opposite direction, the value of is positive.
When calculated counterclockwise, the value of is negative.
If laid off at the terminal side of, the value of r is positive.
If r is terminated at the prolongation through the origin from the terminal side of, it has a negative value.
The equation is given as:
Now lets xonsider: x=rcosθ and y=rsinθ
x2+y2=r2
Now putting the values, we get:
Here we used the concept of polar coordinate system and also the trigonometric ratios to find the solution. So the equation is 
.
