???

Answer 2

Can you help me solve this??

Answer 3

wait a bit

Answer 4

Okay, thank you.

Answer 5

is it
\[4\csc 2x=2\csc ^2xtanx \]

Answer 6

\[4\csc 2x=\frac{ 4 }{ \sin 2x}=\frac{ 4 }{ 2\sin x \cos x }\]

Answer 7

\[4 \csc 2x = 2 \csc^2x \tan x\]

Answer 8

\[=2\csc x\frac{ \sin x }{\cos x }\frac{ 1 }{ \sin x }\]

Answer 9

\[=2\csc^2xtan x\]

Answer 10

Can you explain how you got that answer.

Answer 11

I multiplies numerator and denominator by sin x and 1/sin x =csc x and sin x/cos x=tan x

Answer 12

*multiplied

Answer 13

sin 2x=2 sin x cos x

Answer 14

Thanks a million again!! @jango_IN_DTOWN

Answer 15

write the reasons wherever you use other identities.. The teacher will be happy too.:)
