Question

2sin(3pie/4) = 1 solve for 0 is less than or equal to x less than 2pie

Answer 1

\[\sin (3\pi/4)\]=1/2,\[0\le x \le 2 \pi\]
where is x in question...?

Answer 2

what to solve...?

Answer 3

oh sorry (3pie/4 (x))

Answer 4

ok...x is in multiplication or division..?

Answer 5

multiplication

Answer 6

Oh i solved it!

Answer 7

wow superb!

Answer 8

lol., good:) how many values u got ?

Answer 9

5

Answer 10

:O
how ?

Answer 11

well it says to find within 0- 2pie

Answer 12

so you have to add the period to the reference angle which is x to solve for the other solutions

Answer 13

\[\sin ((3 \pi/4 )x)=1/2\]
\[(3\pi/4)x=\sin^{-1} (1/2)\]
\[(3\pi/4)x=\pi/6,5\pi/6\]
\[x=\pi/6*(4/(3\pi)),(5\pi/6)*(4/(3\pi))\]

Answer 14

Thanks! :)
