How do you name the curve given by the conic #r=4/(1+2sintheta)#?
The polar equation
eccentricity is e. A focus is the pole and the line from the pole away
from the center is the initial line
we get the equation in the given form
This transformation is rotation of the initial line through
For e > 1, the conic is named a hyperbola..
the semi major axis the hyperbola
