For the following questions answer them individually
If x = α secα cosβ, y = b secα sinβ, z = c tan α, then the value of $$\frac{x^2}{a^2}+\frac{y^2}{b^2}-\frac{z^2}{c^2}$$
If $$\frac{x^2}{a^2}+\frac{y^2}{b^2}-\frac{z^2}{c^2}$$ and $$\frac{\sin\alpha}{\sin\beta}=b$$ then the value of $$\sin^{2}\beta$$ in trems of a and b is
The value of $$\frac{\cos^260^{\circ}+4\sec^230^{\circ}-\tan^245^{\circ}}{\sin^230^{\circ}+\cos^230^{\circ}}$$
