Answer 2

sinx=sx

cosx=cx

sx+cx/sx-cx + sx-cx/sx+cx

=(sx+sx)^2/(sx-cx)(sx+cx)+(sx-cx)^2/(sx-cx)(sx+cx)

expanding and simplifying            

=(1+2sxcx+1-2sxcx)/s^2x-c^2x                    (sin^2x=1-cos^2x)

=2/s^2x-c^2x

dividing and multiplying by sec^2x

=2*sec^2x/s^2x*sec^2x-c^2x*sec^2x             (sin^2x*sec^2x=tan^2x)

=2sec^2x/tan^2x-1
