Pair Of Linear Equations In Two Variables Class 11 Notes
Distance Formula
Suppose that there are two points (x1,y1,z1) and (x2,y2,z2) then the distance formula is given as
Section Formulas
Suppose that there are two points (x1,y1,z1) and (x2,y2,z2) are divided into m:n.
Then section formula is given as:
Systems Of Planes
An equation of a plane contains three independent constants, as such a plane is uniquely determined by three independent conditions. If we consider a plane satisfying just two given conditions, its equation will contain one arbitrary constant. If we consider a plane satisfying one given condition, its equation will contain two arbitrary constants.
We give below the equations of some well-known systems of planes:
The equation ax + by + cz + k = 0 represents a system of planes parallel to the plane ax + by + cz + d = 0 d, k are parameters.
The equation ax + by + cz + k = 0 represents a system of planes perpendicular to the line x/a = y/b = z/c .
The equation a1x + b1y + c1z + d1 = 0 + λ(a2x + b2y + c2z + d2 )= 0 a system of planes passing through the intersection of the planes are a1x + b1y + c1z + d1 = 0 and a2x + b2y + c2z + d2 = 0.
where λ is a parameter.
Angle Between Two Planes
Let there are two planes a1x + b1y + c1z + d1 = 0 and a2x + b2y + c2z + d2 = 0
Then the angle between is given as
The Symmetrical Form Of The Equation Of A Line
If a straight line passes through a given point (x1,y1,z1) and has direction cosines l, m, n, then the coordinates of any point on it satisfy the equations
Vector Equations:
Parametric vector equation of the line through a point with position vector a and parallel to the vector b is
where λ is a scalar parameter.
