Why did you take sin theta = root (2/3)?

@indranil costheta=1/√3.

@indranil costheta=1/√3.
how do you know that sin theta is root (2/3)? I mean how did you get it?

@Indranil ,
Cos is adjacent side/hypotenuse
The adjacent side is 1, hypotenuse is √3
Hence, costheta is 1/√3
Knowing this, make a right triangle
You gonna see that opposite side is √2
Sin is opposite side/hypotenuse
Hence, sintheta is √2/√3
