**PROVE :(secA+tanA)2 =(1+sinA)/(1/sinA)**

PROVE :(secA+tanA)2 =(1+sinA)/(1/sinA)

**Answer**

[tex]A=x\\\\(secx+tanx)^2=\frac{1+sinx}{1-sinx}\\\\L=\left(\frac{1}{cosx}+\frac{sinx}{cosx}

ight)^2=\left(\frac{1+sinx}{cosx}

ight)^2=\frac{(1+sinx)^2}{cos^2x}\\\\=\frac{(1+sinx)^2}{1-sin^2x}=\frac{(1+sinx)^2}{1^2-sin^2x}=\frac{(1+sinx)^2}{(1-sinx)(1+sinx)}=\frac{1+sinx}{1-sinx}=R[/tex]
