if tan tita plus sin tita=mtan tita - sin tita=nshow that m sq-n sq=4r

1.	if tan tita plus sin tita=mtan tita - sin tita=nshow that m sq-n sq=4root mn
Answer» L.h.sMsq - Nsq= (tanA+sinA)sq -(tanA-sinA)sq=4tanAsinA.R.h.s4√mn=4√(tanA+sinA)(tanA-sinA)=4√tanAsq - sinAsq=4√sinAsq/cosAsq - sinAsq=4√(sinAsq-sinAsq×cosAsq)/cosA=4sinA/cosA√1-cosAsq=4tanA√sinAsq=4tanAsinA=L.h.s (proved)
