1.5. PLANES 67 be two vectors representing the sides of the triangle at this vertex. Then the parametrization −→ p ( s,t ) = −→ p 0 + s −→ v + t −→ w = −−→ O P + s −−→ PQ + t −→ PR describes the plane containing our triangle; the vertices have position vectors −−→ O P = −→ p 0 = −→ p (0 , 0) −−→ O Q = −→ p 0 + −→ v = −→ p (1 , 0) −−→ O R = −→ p 0 −→ w = −→ p (0 , 1) . For example, the three points one unit out along the three (positive) coordinate axes P (1 , 0 , 0) ( −−→ O P = −→ ı ) Q (0 , 1 , 0) ( −−→ O Q = −→ ) R (0 , 0 , 1) ( −−→ O R = −→ k ) determine the plane with parametrization −→ p (

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
