If sin x =3/7 x in quadrant I, then find (without finding x)

sin(2x) =
cos(2x) =
tan(2x) =

According to the information given, the trigonometric functions are given by:

The measures of the sine and of the cosine of an angle x are related by the following equation:

Since

Now, the identities are applied:

Tangent is sine divided by cosine, hence:
