It is known that there are two intersections between a straight line passing through the right focus of hyperbola x2a2-y2b2 = 1 (a > 0, b > 0) and the right branch of hyperbola with an inclination angle of 45 degrees, then the value range of eccentricity e of hyperbola is______ .

It is known that there are two intersections between a straight line passing through the right focus of hyperbola x2a2-y2b2 = 1 (a > 0, b > 0) and the right branch of hyperbola with an inclination angle of 45 degrees, then the value range of eccentricity e of hyperbola is______ .

In order to make the straight line and hyperbola have two intersections, we need to make the slope of one of the asymptote equations of hyperbola less than the slope of the straight line, that is ba < tan45 ° = 1, that is B < a ∵ B = C2 − A2 ∵ C2 − A2 < a. the range of E is (1,2), so the answer is (1,2)
