Question

Verify the identity.

4 csc 2x = 2 csc^2(x) tan x

Answer 1

help me!!!!:(

Answer 2

hi there

Answer 3

sure simple

Answer 4

@mathsmind hi!!

Answer 5

ok now step one

Answer 6

okay!

Answer 7

sin2(x)=2sin(x)cos(x)

Answer 8

sorry be patient my net is slow

Answer 9

csc(x) = 1/ sin(x)

Answer 10

so 4csc(2x) = 4/sin(2x)

Answer 11

you agree so far

Answer 12

4/sin(2x)=2/sin(x)cos(x)

Answer 13

now am going to use the equation editor to make it clearer for u ok

Answer 14

we are going to multiply both sides by sin(x)/sin(x)

Answer 15

okay!!

Answer 16

\[=\frac{ 2 }{ \sin(x)\cos(x) }\frac{ \sin(x) }{ \sin(x) }\]

Answer 17

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

Answer 18

tan(x) = sin(x)/cos(x), and 2/sin^(x) = 2csc^2(x)

Answer 19

\[=2 \tan(x)\csc^2(x)\]

Answer 20

this proves your claim

Answer 21

i hope this helped
