the question is as follows: the vertex angle of a double napped cone is 105 degrees the angle 0 is the angle measured from the axis to the cutting plane. for what angle 0, or range of values for 0, does the cutting plane need to interescet the conical surface in order to generate each of the following conics?

a. Hyperbola

b. ellipse

C.circle

d. parabola

how would I go do this question cuz first off I don't get what it wants from me! :confused:
