More about this book
Most students read the textbook once and run out of time for a second revision. This formula sheet book is made for that gap: it keeps only what the exam asks, in the same order as the NCERT chapters, so you can revise the full syllabus three or four times before the exam.
Ordering: pay online to get 10% off and free delivery. Cash on delivery is available for ₹80 extra.

MATHEMATICS · CHAPTER 11148
11.6 PLANES THROUGH THE LINE OF INTERSECTION OF TWO PLANES
Two planes that are not parallel meet in a straight line. Suppose the planes π₁ and π₂ are given in vector form by r · n₁ = d₁ and r · n₂ = d₂. Every point lying on their common line must satisfy both these equations simultaneously. If both equations hold for a point, then so does the equation obtained by adding the first to λ times the second, whatever real number λ may be. Hence the family of planes
r · (n₁ + λn₂) = d₁ + λd₂
contains every plane that passes through the line of intersection of π₁ and π₂; a particular member of the family is selected by using one more condition, such as a point through which the plane must pass.
The angle between two planes is measured by the angle between their normals. Since the normals may be drawn in either sense, both θ and 180° − θ could be called the angle between the planes, and by convention the acute angle is chosen. In Cartesian form, if the direction ratios of the normals are A₁, B₁, C₁ and A₂, B₂, C₂, then
cos θ = |A₁A₂ + B₁B₂ + C₁C₂| / (√(A₁² + B₁² + C₁²) √(A₂² + B₂² + C₂²))
