NCERT Solutions Class 12 Maths Chapter 10 Vector Algebra
NCERT solutions for class 12 maths chapter 10 vector algebra elaborates on a very important concept that is used in both mathematics and physics known as vectors. In daily life, we come across many queries such as what is the height of a tree? Or how hard should a ball be hit to reach a goal? The answers to such questions only consist of magnitude. Such quantities are called scalars. However, suppose we also want to find the direction in which a tree is growing or the direction in which the ball needs to be hit to reach the goal then we have to resort to using another quantity known as a vector. Thus, we can say that a quantity having both direction and magnitude is called a vector. In mathematical and physical studies, we require both scalars such as length, mass, time, distance, speed, area, volume, temperature as well as vectors such as displacement, velocity, acceleration, force, weight, etc. NCERT solutions class 12 maths chapter 10 shows kids how to solve questions using vectors.
The sums in the Class 12 maths NCERT solutions chapter 10 are based on real-life examples that enable kids to relate to this concept. The chapter starts with the introduction of some basic vector concepts and builds on those to give a good understanding of complicated topics. The best part about the NCERT solutions Chapter 10 vector algebra is that it uses vernacular and simple language to convey difficult sections so that students of all intelligence quotas can grasp them easily.

The word vector has been derived from the Latin word vectus, which means “to carry”. The ideas of modern vector theory date from around 1800 when Caspar Wessel (1745-1818) and Jean Robert Argand (1768-1822) described how to give the geometric interpretation of a complex number with the help of a directed line segment in a coordinate plane. Further studies made by mathematicians resulted in the topic as we know it today. The links to the NCERT solutions class 12 maths can be found below that contain several such facts and tips to help kids study the subject matter with enthusiasm.

List of Formulas in NCERT Solutions Class 12 Maths Chapter 10
NCERT solutions class 12 maths chapter 10 see the use of many formulas that help in performing arithmetic operations on vectors. The same laws that apply to whole numbers or scalars do not work in the case of vectors as these quantities have direction as well. Thus, by taking this element into account the computations for vectors differ. Additionally, there are many geometrical implications of vectors that are described in this chapter and these include further formulas as well as procedures. The formulas in the NCERT solutions for class 12 maths chapter 10 are given below. Kids should also make a formula chart so as to revise them quickly.
- Let S and T be two vectors then the dot product is given by S.T = |S| |T| cos θ.
- If θ = 0°, meaning both S and T are in the same direction then T = |S| |T|.
- If θ = 90°, meaning S and T are orthogonal then T = 0.
- If we have two vectors S = (S1, S2, S3 ….. Sn) and T = (T1, T2, T3 ….. Tn) then the dot product is given as S.T = (S1T1 + S2T2 + S3T3 ….. SnTn)
