I don't know how to solve this i need to verify the identity?
\n" ); document.write( "(1+sec(-θ))/(sin(-θ)+tan(-θ))=(1-sec(θ))/(sin(θ)-tan(θ))
\n" ); document.write( "**
\n" ); document.write( "sec(-θ)=sec(θ)
\n" ); document.write( "sin(-θ)=-sin(θ)
\n" ); document.write( "tan(-θ)=-tan(θ)
\n" ); document.write( "starting with left side
\n" ); document.write( "(1+sec(-θ))/(sin(-θ)+tan(-θ))
\n" ); document.write( "[1+sec(θ)]/-sin(θ)-tan(θ)
\n" ); document.write( "[1+sec(θ)]/-[sin(θ)+tan(θ)]≠right side
\n" ); document.write( "Identity cannot be verified \n" ); document.write( "
