Given an inclined plane with inclination angle $\omega$ (sharp angle) and center $O$ .
Let points P $(x_0,y_0)$ and Q $(x_1,y_1)$ be in quadrant I. Determine the area of triangle OPQ !

Convert to vectors in 3-D and use half the absolute value of the cross product of the vectors.

Inclined with angle $\omega$ relative to what? An uninclined plane? And what is the "center" of a plane? Are points P and Q in the inclined plane or in the "uninclined" plane? Is O the origin? In which plane is the coordinate system?
