Key Calculus Terms and definitions covered in this textbook
  • Additive inverse of a complex number

    The opposite of a + bi, or -a - bi

  • Arcsecant function

    See Inverse secant function.

  • Arctangent function

    See Inverse tangent function.

  • Conic section (or conic)

    A curve obtained by intersecting a double-napped right circular cone with a plane

  • Discriminant

    For the equation ax 2 + bx + c, the expression b2 - 4ac; for the equation Ax2 + Bxy + Cy2 + Dx + Ey + F = 0, the expression B2 - 4AC

  • Eccentricity

    A nonnegative number that specifies how off-center the focus of a conic is

  • First-degree equation in x , y, and z

    An equation that can be written in the form.

  • Focal width of a parabola

    The length of the chord through the focus and perpendicular to the axis.

  • Lemniscate

    A graph of a polar equation of the form r2 = a2 sin 2u or r 2 = a2 cos 2u.

  • Linear inequality in x

    An inequality that can be written in the form ax + b < 0 ,ax + b … 0 , ax + b > 0, or ax + b Ú 0, where a and b are real numbers and a Z 0

  • Linear regression line

    The line for which the sum of the squares of the residuals is the smallest possible

  • Minor axis

    The perpendicular bisector of the major axis of an ellipse with endpoints on the ellipse.

  • Origin

    The number zero on a number line, or the point where the x- and y-axes cross in the Cartesian coordinate system, or the point where the x-, y-, and z-axes cross in Cartesian three-dimensional space

  • Orthogonal vectors

    Two vectors u and v with u x v = 0.

  • Parameter

    See Parametric equations.

  • Quotient rule of logarithms

    logb a R S b = logb R - logb S, R > 0, S > 0

  • Relevant domain

    The portion of the domain applicable to the situation being modeled.

  • Second-degree equation in two variables

    Ax 2 + Bxy + Cy2 + Dx + Ey + F = 0, where A, B, and C are not all zero.

  • Standard representation of a vector

    A representative arrow with its initial point at the origin

  • Vertices of a hyperbola

    The points where a hyperbola intersects the line containing its foci.
