Question

if tan theta + sin theta equal to M and tan theta minus sin theta equal to N prove (m square minus n square)= 16mn

Answer 1

m ^2=tan^2x+sin^2x+2tanxsinx
n^2=tan^2x+sin^2x-2tanxsinx
subtract the equations
which is equal to 16mn

Answer 2

hey dear friend jus check ur ques I think vha PR (m sq - n sq)whole sq hoga
jus check it
