For the following questions answer them individually
If $$tanθ = \frac{a}{b}$$, then $$\frac{a sin \theta + b cos \theta}{a sin \theta - b cos\theta}$$ is
The value of $$\frac{sin39^{\circ}}{cos51^{\circ}}$$ + $$2 tan11^{\circ} tan31^{\circ} tan45^{\circ} tan59^{\circ} tan79^{\circ}$$ - $$3(sin^{2}21^{\circ} + sin^{2}69^{\circ})$$ is
The value of $$(\sqrt{5}+\sqrt{3})(\frac{3\sqrt{3}}{\sqrt{5}+\sqrt{2}} - \frac{\sqrt{5}}{\sqrt{3}+\sqrt{2}})$$ is
If $$\frac{3-5x}{x} + \frac{3-5y}{y} + \frac{3-5z}{z} = 0 $$, the value of $$\frac{1}{x} + \frac{1}{y} + \frac{1}{z}$$ is
