Because the electric field has both a magnitude and a direction, it is termed a vector quantity, and that is indicated by printing its symbol, E, in bold typeface as in equations (I) and (II). Figure ...

In particular you MUST add and subtract them like vectors. Do not plug numbers into a vector equation or formula. We have shown you a simple geometrical representation of adding and subtracting ...

the so-called "father of algebra," established the fundamentals for solving equations that we began to set the foundations for modern mathematics. In this excerpt from her new book "Vector ...

IN this volume the vector equation of mass acceleration commonly known as Newton's laws is applied to the “law of areas,” the problems of harmonic and oscillatory motion, the brachistochrone ...

Hamilton also developed a compact notation to make his equations concise and elegant. He used a Greek letter to denote a quaternion or vector, but today, following Heaviside, it is common to use a ...
