{{{1-(cos^(2)(theta))/(1+sin(theta))=sin(theta)}}}............{{{cos^(2)(theta)=1-sin^2(theta)}}}

{{{1-(1-sin^2(theta))/(1+sin(theta))=sin(theta)}}}


{{{1-((1-sin(theta))(1+sin(theta)))/(1+sin(theta))=sin(theta)}}}


{{{1-((1-sin(theta))(1+sin(theta)))/(1+sin(theta))=sin(theta)}}}


{{{1-(1-sin(theta))=sin(theta)}}}


{{{1-1+sin(theta)=sin(theta)}}}


{{{sin(theta)=sin(theta)}}}
