If tan θ=ab, then a sin θ+b cos θa sin θ-b cos θis equal to(a) a2 – InterviewSolution

1.	If tan θ=ab, then a sin θ+b cos θa sin θ-b cos θis equal to(a) a2+b2a2-b2(b) a2-b2a2+b2(c) a+ba-b(s) a-ba+b
Answer» If $\tan θ = \frac{a}{b}, then \frac{a \sin θ + b \cos θ}{a \sin θ - b \cos θ}$ is equal to (a) $\frac{a^{2} + b^{2}}{a^{2} - b^{2}}$ (b) $\frac{a^{2} - b^{2}}{a^{2} + b^{2}}$ (c) $\frac{a + b}{a - b}$ (s) $\frac{a - b}{a + b}$
