Question
CBSEENMA11015150

Find the coordinates of vertex, focus, equations of axis, tangent at vertex, directrix, latus rectum of the following equation:
straight x squared equals negative 9 ay comma space straight a greater than 0



Solution

Solution not provided.
Ans. Vertex - (0, 0)
       Focus - WiredFaculty
       Axis - (x = 0)
       Tangent at vertex - (y = 0)
       directrix - straight y minus 9 over 4 straight a equals 0 space or space 4 straight y minus 9 straight a equals 0
       latus rectum - (9a)
