[tex]\\ \rm\Rrightarrow \dfrac{secA-cosA}{secA}[/tex]

[tex]\\ \rm\Rrightarrow \dfrac{1/cosA-cosA}{secA}[/tex]

[tex]\\ \rm\Rrightarrow \dfrac{1-cosA/cosA}{secA}[/tex]

[tex]\\ \rm\Rrightarrow \dfrac{2sin^2(A/2)/cosA}{1/cosA}[/tex]

[tex]\\ \rm\Rrightarrow 2sin^2(A/2)[/tex]

[tex]\\ \rm\Rrightarrow Sin^2A[/tex]
