What is the equation of a hyperbola with a = 1 and c = 9? Assume that the transverse axis is horizontal.

A=1 , c=9

y²/a²-x²/b²=1

c²=a²+b²

b²=c²-a²

b²= 9²-1²

b²=8

y²/1²-x²/8=1

y²- x²/8=1 is the equation of hyperbola.

y²/a²-x²/b²=1

c²=a²+b²

b²=c²-a²

b²= 9²-1²

b²=8

y²/1²-x²/8=1

y²- x²/8=1 is the equation of hyperbola.
