The tangent of the angle between the lines whose intercepts on the axe – InterviewSolution

1.	The tangent of the angle between the lines whose intercepts on the axes are a, –b and b, –a respectively, is(a) a2-b2ab(b) b2-a22(c) b2-a22ab(d) none of these
Answer» The tangent of the angle between the lines whose intercepts on the axes are a, –b and b, –a respectively, is (a) $\frac{a^{2} - b^{2}}{a b}$ (b) $\frac{b^{2} - a^{2}}{2}$ (c) $\frac{b^{2} - a^{2}}{2 a b}$ (d) none of these
