# Solution - Find the cartesian form of the equation of the plane - HSC Science (Computer Science) 12th Board Exam - Mathematics and Statistics

#### Question

Find the cartesian form of the equation of the plane bar r=(hati+hatj)+s(hati-hatj+2hatk)+t(hati+2hatj+hatj)

#### Solution

The equation barr=bara+sbarb+tbarc represents a plane passing through a point having position vector a and parallel to the vectors b and c .

Here, bara=hati+hatj, barb=hati-hatj+2hatk and barc=hati+2hatj+hatk

The given plane is perpendicular to the vector barn

Vector equation of the plane in scalar product form is barr.barn=bara.barn

therefore x(-5)+y(1)+z(3)=-4

therefore -5x+y+3z=-4

therefore 5x-y-3z=4

which is the cartesian form of the equation of the plane

Is there an error in this question or solution?
