Transform the polar equation into an equation in rectangular coordinates. Graph the resulting equation in the rectangular coordinate system. Identify the graph.

r = 2 sin ?

Answer 1

Always remember these formulas, When dealing with transformations between polar and Cartesian coordinates,

• 
• 
• 

we have

to convert this into cartesian coordinates,

ie,

  This will be the cartisian coordinates of the polar equation

The graph will have circular shape
