To prove: The distance between F 1 and V 2 is c + a and the distance between F 2 and V 2 is c − a and the difference between these distances is 2 a . The given figure is:
To prove: The distance between F 1 and V 2 is c + a and the distance between F 2 and V 2 is c − a and the difference between these distances is 2 a . The given figure is:
Solution Summary: The author analyzes the distance between F_1 and V2, and the difference between these distances.
Toprove: The distance between F1 and V2 is c+a and the distance between F2 and V2 is c−a and the difference between these distances is 2a . The given figure is:
(b)
To determine
Tocalculate: The expression that represents the difference of the distance from F1 to x,y and from F2 to x,y .
(c)
To determine
Toprove: The equation x+c2+y2−x−c2+y2=2a can be written as cx−a2=ax−c2+y2 .
(d)
To determine
Toprove: The equation cx−a2=ax−c2+y2 can be written as c2−a2x2−a2y2=a2c2−a2 .
(e)
To determine
Toprove: The equation c2−a2x2−a2y2=a2c2−a2 can be written as x2a2−y2b2=1 .
