Magnitude of a vector a is denoted by a or a.
Vector formulas pdf. USEFUL STUFF Revision of Basic Vectors A scalar is a physical quantity with magnitude only A vector is a physical quantity with magnitude and direction A unit vector has magnitude one. In Cartesian coordinates a a 1e 1 a 2e 2 a 3e 3 a 1a 2a 3 Magnitude. One Sheet Vector Review Vectors are numerical objects characterized by a mag-nitude and a direction.
123 I Two definitions for the dot product. I Dot product and orthogonal projections. For example recall the Section Formula from Level 1.
Dot product and vector projections Sect. And denote vectors by lower case boldface type such as u v w. Two arrows represent the same vector if they have the same length and are parallel see figure.
Displacement velocity momentum force and acceleration are all vector quantities. In vector or multivariable calculus we will deal with functions of two or three variables usually xy or xyz respectively. 113 The three numbers A i i 123 are called the Cartesian components of the vector A.
I Dot product in vector components. Vector Algebra A vector has direction and magnitude both but scalar has only magnitude. As the set fe igforms a basis for R3 the vector A may be written as a linear combination of the e i.
Vector Algebra x 131. To distinguish between scalars and vectors we will denote scalars by lower case italic type such as a b c etc. A A 1e 1 A 2e 2 A 3e 3.
