I need details for the below question.

1. Sketch the plane curve: y = 1/x (in the xy-plane), and find: a) the two unit vectors tangent to the curve at the point P(1, 1), and b) the two unit vectors normal to the curve at the point P(1, 1) . Given the points: A(- 1, 2, 3), B(2, 1, 1) and C(1, 0, 3), c) find the area of triangle ABC, d ) find an equation for the plane containing A, B and C, e ) find the distance between the origin and the line containing A and B
