Graphs to polar equations Find a polar equation for the coinc sections in the figures.

Solution 55REFrom the given figure we have to find the polar equation of a conicThe graph is shown below: The graph is shown below From the given figure vertices are )We have 2a = Center is ( 0.)Distance from the centre to focus is ae = Now one directrix is y = - if the center is (0,0)But here the centre is (0,) hence y = - y = -+ + Hence d= 3Hence the equation of a conic system is r =
