So, for a particular vector, there are infinite planes which are perpendicular to it. The graph of the plane -2x-3y+z=2 is shown with its normal vector. ∴ Vector equation of plane is [ ⃗−( ̂+ ̂ − ̂ )] . Find your group chat here >>, Uni students may not return until February. Here, the length is the magnitude and the arrowhead show the direction. The Cartesian plane, also known as the coordinate plane, is a two-dimensional plane generated by two perpendicular lines described as the x-axis (horizontal axis) and the y-axis (vertical axis). Here are a couple of examples: We know that: ax + by + cz + d = 0 —————(i). 0 ⃗ = 0 Since, the above equation is satisfied for all values of ⃗, Therefore, there will be infinite planes passing through the given 3 collinear points. By plugging in the values of the points A, B, and C into equation (i), we get the following: Solving these equations gives us a = 0, c = \[\frac{1}{2}\] b, d = —2b ———————(ii), Therefore, the equation of the plane with the three non-collinear points A, B and C is. What are Collinear and Non-Collinear Points? A position vector basically defines the position of a particular point in a three dimensional cartesian plane system, with respect to an origin point. Line in 3D is determined by a point and a directional vector. We have a brilliant team of more than 60 Support Team members looking after discussions on The Student Room, helping to make it a fun, safe and useful place to hang out. The exact position of the point on the Cartesian plane can be determined using coordinates that are written in the form of an ordered pair (x, y). © Copyright The Student Room 2017 all rights reserved. ah.. had a feeling it would involve simultaneous equations. Using this method, we can find the equation of a plane if we know three points. Equation of a plane. Two points are always collinear, because the line connecting both of them is always present. From this we can get the parametric equations of the line. a) Find a parametric equation of the plane P through the two points (-2,3,1) and (1,4,-3) and parallel to the vector v=(-1,5,2) b) Find the Cartesian equation of the plane through (5,3,-8) with normal vector n=(3,1,-1).
