Evaluate the indefinite integral:

Make the following substitution:

and then, the integral (i) becomes

Integrate it by applying the power rule:

Now, substitute back for u = sin x, so the result is given in terms of x:

Skew lines are lines that are not parallel and do not intersect.
BD, AB, FH, EF intersect BF. They are not skew to BF.
DH, CG, AE are parallel to BF. They are not skew to BF.
CD, AC, GH, EG are neither parallel nor do they intersect BF, so they are skew to BF
