Question

solve 3csc^2x-4=0

Answer 1

Add 4 on both sides.

Answer 2

ok

Answer 3

Did you do it?

Answer 4

yes

Answer 5

Now divide by 3 on both sides. You get csc^2 x= something

Take square root and you get the answer.

Answer 6

so csc=2/rt3?

Answer 7

or sin=rt3/2

Answer 8

????

Answer 9

sin(2x) = sqrt(3) / 2
2x = ?

Answer 10

sin(x)=rt3/2*

Answer 11

2/root 3 is right!!

Answer 12

so x=pi/3 and 2pi/3 correct?

Answer 13

IM SOLVING FOR X ARVINDG

Answer 14

Indeed so sin 60=root 3/2

ie pi/3

Answer 15

Yes well done!

Answer 16

and 2pi/3?

Answer 17

sin(2x) = sqrt(3) / 2
2x = pi/3 or 2pi/3
x = pi/6 or pi/3
sine is a periodic function and so any multiples of 2pi will also give you the same sine value.
x = pi/6 +/- n(2pi) or pi/3 +/- n(2pi) where n = 0, 1, 2, 3, ...
