Question

(sin2x)/(1+cos2x)+(1+cos2x)/(sin2x)=2/(sin2x)
simplify..

Answer 1

have any idea?:)

Answer 2

maybe start with
\[1+\cos(2x)=2\cos^2(x)\]

Answer 3

why 1+cos(2x) = 2cos^2(x)??

Answer 4

why is it true or why use it?

Answer 5

why it is true..?

Answer 6

because
\[\cos(2x)=2\cos^2(x)-1\]

Answer 7

also
\[\sin(2x)=2\cos(x)\sin(x)\] use these and you will probably get the answer quickly

Answer 8

or maybe just add up and see what we get

Answer 9

\[\frac{(1+\cos(2x))^2+\sin(2x)^2}{(1+\cos(2x))\sin(2x)}\]

Answer 10

\[\frac{1+2\cos(2x)+\cos^2(2x)+\sin^2(2x)}{(1+\cos(2x))\sin(2x)}\]
\[\frac{2+2\cos(2x)}{(1+\cos(2x))(\sin(2x)}\]
\[\frac{2(1+\cos(2x)}{(1+\cos(2x))\sin(2x)}\]
\[\frac{2}{\sin(2x)}\]

Answer 11

thanks :))
