[1+sinx]/[1+cscx]=tanx/secx

=[1+sinx]/[1+1/sinx]

=[1+sinx]/[(sinx+1)/sinx]

=[1+sinx]*[sinx/(sinx+1)]

=[sinx+sin^2x]/[sinx+1]

=[sinx+(1-cos^2x)]/[sinx+1]

=???

This is where I'm stuck. Can someone help me. Please check what I got is right so far it's possible that I made a mistake somewhere.

Please and Thank you

**Reiny**, Sunday, March 11, 2012 at 11:59pmLS = (1 + sinx)/(1 + 1/sinx)

= (1 + sinx)/( ( sinx + 1)/sinx )

= (1 + sinx) ( sinx/(1+sinx))

= sinx

RS = (sinx/cosx)(cosx)

= sinx

= LS
