ABSTRACT
Transposing formulae is a basic skill required in all aspects of engineering. The ability to transpose formulae is yet another stepping stone on the way to having confidence to handle engineering mathematics and science. This chapter aims to define ‘subject of the formula’ and discusses transpose equations whose terms are connected by plus and/or minus signs. It examines transpose equations that involve fractions and explores transpose equations that contain a root or power and explores transpose equations in which the subject appears in more than one term. Whenever the prospective new subject is a squared term, that term is isolated on the left hand side, and then the square root of both sides of the equation is taken.
