Answer 2

x²/9-y²/16=1

Step-by-step explanation:

x=3sec0

Therefore, x/3=sec0

y=4tan0

Therefore, y/4=tan0

By using trigonometric indentity,

sec²0=tan²0+1

Substitute the above value of sec and tan to the identity,

Therefore,

(x/3)²=(y/4)²+1

(x/3)²-(y/4)²=1

x²/9-y²/16=1

Hence, 0 is eliminated.

if you want to solve it further, then you can

but this much is enough.
