If from a point `P(a ,b ,c)` prpendiculars `P Aa n dP B` are drawn to `y za n dz x-p l a n e s ,` find the eqution of th plane `O A Bdot`

Text Solution

Verified by Experts

The coordinates of A and B are (0,b,c) and (a,0,c) respectively.
The equation of the plane passing through
`O(0,0,0),A(0,b,0)` and `B(a,0,c) ` is given by
`|[x,y,z],[0,b,0],[a,c,0]|` `=>bcx+acy−abz=0`
