Explanation:
To convert from
#color(blue)"cartesian to polar form"#
#color(orange)"Reminder"#
#color(red)(|bar(ul(color(white)(a/a)color(black)(x=rcostheta , y=rsintheta)color(white)(a/a)|)))#
#rArr9(color(red)(rcostheta))^2-4(color(red)(rsintheta))^2=36#
#rArr9r^2cos^2theta-4r^2sin^2theta=36#
#rArrr^2(9cos^2theta-4sin^2theta)=36#
#rArrr^2=36/(9cos^2theta-4sin^2theta)#
