You can put this solution on YOUR website!
polar coordinates are written in the from (r, theta) were r is the radius and theta is the anti-clockwise angle for the positive x-axis.
\n" ); document.write( "The radius is easy to calculate:
\n" ); document.write( " $\"r=sqrt%28x%5E2%2By%5E2%29\"$
\n" ); document.write( "and theta can be found using:
\n" ); document.write( " $\"theta=atan%28y%2Fx%29\"$
\n" ); document.write( "where atan is the inverse of the tan function.\r
\n" ); document.write( "\n" ); document.write( "If x=0, the angle is either 90 or 180 degrees. If y>0 and x=0, theta is 90 degrees.
\n" ); document.write( "If y<0 and x=0, theta is 180 degrees.\r
\n" ); document.write( "\n" ); document.write( "In polar form, (0,-3) is (3,180) where theta is measured in degrees, or
\n" ); document.write( "if the angle is in radians: r=3, theta=0.75*pi (3, 0.75pi)\r
