Question

identify the equation as either an identity or not plzz help meeeeeee

sin x/1-cos x+sin x/1+cos x=2csc x

Answer 1

cos2x=1-2sin^2x=2cos^x-1
use them for 1-cosx and 1+cosx

Answer 2

can u help me plz i didnt get get at all

Answer 3

cox=1-2sin^2(x/2)
1-cosx =2sin^x/2
1+cosx=2cos^2x/2

Answer 4

or u could solve normally
sinx/1-cosx + sinx/1+cosx
=sinx(1-cosx+1+cosx)/1-cos^2x
=2sinx/sin^2x
=2/sinx
=2cosecx
this method is quick i guesss

Answer 5

can u write it on the board so i can see it plz if u dont mind i t

Answer 6

so is it identity or not
