Question

please solve it as early as possible....​

Answer 1

Answer:

(1+cosX) 1+cosX (1+cosX)^2

sqrt ---------- × -------- =sqrt ----------------

(1-cosX) 1+cosX (1-cos^2X)

(1+cosX)^2 1+cosx 1 cosX

sqrt -------------- = --------- = ------ + --------

sin^2X sinx sinX sinX

= cosecX + cot X

since,

1-cos^2X = sin^2X

^= symbol of square

sqrt= square root

i hope this is finest answer.if any query messege me.

plz mark me as brainliest. nd follow me.

Answer 2
