I have a small question about one short sentence appearing in page : $290$ of the following electronic textbook : https://scholar.harvard.edu/files/joeharris/files/000-final-3264.pdf
- The short sentence says :
Given five general plane conics $ C_1 , \dots , C_5 $. How many smooth conics are tangent to all five ?
- Question :
What do we mean by saying that a smooth conic is tangent to five general plane conics $ C_1 , \dots , C_5 $ ?
Thanks in advance for your help.
