InverseTrigFunctions[edit source]
  • and defines the arcsine function as the inverse of the sine. Similarly, is called the arctangent, or the inverse tangent, and is called arccosine, or the inverse cosine and so forth. In general, and for any function and its inverse. Complexities occur whenever the inverse is not a true function; for example, since , the inverse is multi-valued:

  • is the Riemann sum representation of the integral of f(x) from x=a to x=b. It is the area under the curve, with contributions from f(x)<0 being negative (if a>b). The sum equals the integral in the limit that the widths of all the intervals vanish (Δxj→0).

  • and are the x and y components of a displacement from the origin to some point. The inverse transformations are:
  • , and
  • , which is multi-valued and therefore not a true function.
  •   and     are called the x and y components of vector A, respectively.
  • is called the magnitude,norm (or sometimes absolute value) of vector A.
  • Omission of the arrow indicates that the quantity is the scalar magnitude of that vector. Another notation that distinguishes between a vector and a scalar is boldface font: A is a vector and A A  is the scalar magnitude.

UnitVectors[edit source]

  • A unit vector is any vector with unit magnitude equal to one. For any nonzero vector, is a unit vector. An important set of unit vectors is the orthonormal basis associated with Cartesian coordinates:
  • The basis vectors are also written as , so that any vector may be written . Even more elegance is achieved by labeling the directions with integers:
