WebAdding Vectors We can then add vectors by adding the x parts and adding the y parts: The vector (8, 13) and the vector (26, 7) add up to the vector (34, 20) Example: add the vectors a = (8, 13) and b = (26, 7) c = a + b c = (8, 13) + (26, 7) = (8+26, 13+7) = (34, 20) When we break up a vector like that, each part is called a component: Coords Reset WebThe 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 .
