You try putting A=tan-1(3)

in which you would need to determine sinA.

ahhh so could I write [tex]sinA = \theta[/tex]?

Well I was thinking more along the lines of if A=arctan(3), then you can get tanA

and your problem was to find sin(arctan(3)) which becomes sin(A), which you can find by drawing suitable right angled triangles.
