I'm going to assume you mean (sin 2x)(tan x + cot x) = 2.
sin 2x = 2 sin x cos x.
tan x = sin x / cos x
cot x = cos x / sin x
Distributing:
2 sin^2 x + 2 cos^2 x = 2
2 = 2
So, it works for all values of x.

Hey dear
It's too easy
Sin2x(tanx+cotx)
= sin2x=2sinx*cosx .
2sin*cosx ( since/cosx+cos,X/sinx/)
2sinx(sin^2x+cos^2x)/sinx*cos X
here sinx * cosx cancelled
then , remaining . , 2 (1)
= 2 RHS proved .
Hope it's helped you ....plz marks as Brainleist answer
