Question

What are polar and cartesian?

Answer 1

Cartesian Coordinate System:

• The cartesian coordinate system is a $2$-D system using a rectilinear grid.
• Points are represented in the form of coordinates $\left(x,y\right)$ in two-dimension with respect to $x$-axis and $y$-axis.

Polar Coordinate System:

• The polar coordinate system is a $2$-D system using a polar grid.
• This system is used to locate a point by giving a distance from a fixed point and an angle from some fixed direction.
• Point are represented in the form $\left(r,\theta \right)$.
