11Consider (x2/a2)-(y2/b2) =1.
this intersects x-axis at (±a,0) and doesn't intersect y-axis at all. So why do we find (0,±b) ?????????
for a hyperbola with x-axis as the axis which the hyperbola intersects, why do why bother to find (0,±b).

62what do u mean find (0,±b) !!!
It is a fixed point already!!!
If you are asking for the physical significance.. it is a different question!
1YES THIS WAS MY QUESTION... AN EVER UNANSWERED DOUBT...
WAT IS THIS 'b' IN THE EQUATION??
1'b' is actually a derived term which is used to give an analogy to the form of equation used for ellipse.
b≡√c2-a2
'c' being focal distance
see for reference
