How to work out a vector
WebWe can use vector components and Pythagoras’ theorem to find the magnitude of the vector. The length of a vector is its absolute value and we use the modulus symbol. Here is the formula: \lvert \textbf {a} \rvert = \sqrt {x^2+y^2} ∣a∣ = x2 +y2 E.g. \lvert \textbf {a} \rvert = \sqrt {x^2+y^2}=\sqrt {5^2+2^2}=\sqrt {29} ∣a∣ = x2 +y2 = 52 +22 = 29 WebFree vectors GCSE maths revision guide, including step by step examples, exam questions and free worksheet.
