• correlation

  When two sets of data are strongly linked together we say they have a high correlation. The word correlation is made of co- (meaning "together"), and relation. Correlation is positive when the values increase together. Correlation is negative when one value decreases as the other increases.
• correlation coefficient

  A number that is a measure of the strength and direction of the correlation between two variables
• corresponding angles

  When two lines are crossed by another line (which is called the Transversal), the angles in matching corners are called corresponding angles. Example: a and e are corresponding angles. When the two lines are parallel Corresponding Angles are equal.
• cosecant

  In a right triangle, the cosecant of an angle is the length of the hypotenuse divided by the length of the opposite side. (see trigonometric function)
• cosine

  In a right angled triangle, the cosine of an angle is: the length of the adjacent side divided by the length of the hypotenuse.
• cotangent

  In a right-angled triangle, the cotangent of an angle is: the length of the adjacent side divided by the length of the side opposite the angle.
• co-terminal angles

  Co-terminal Angles are angles who share the same initial side and terminal sides. Finding co-terminal angles is as simple as adding or subtracting 360° or 2π to each angle, depending on whether the given angle is in degrees or radians. There are an infinite number of co-terminal angles that can be found.
• critical point

  A critical point of a differentiable function of a real or complex variable is any value in its domain where its derivative is 0.
• cross product

  The cross product a × b is defined as a vector c that is perpendicular (orthogonal) to both a and b, with a direction given by the right-hand rule and a magnitude equal to the area of the parallelogram that the vectors span.
• cross section

  A view into the inside of something made by cutting through it. In geometry it is the shape made when a solid is cut through parallel to the base.
• cube

  In geometry, a cube is a three-dimensional solid object with six square faces, twelve straight edges, and eight vertices (corners). All the interior angles in a cube are right angles, and all its edges are of equal length.
• cubic polynomial

  Is a polynomial of degree 3. An equation involving a cubic polynomial is called a cubic equation.
• curvature

  Is any of a number of loosely related concepts in different areas of geometry. Smaller circles bend more sharply, and hence have higher curvature. The curvature of a smooth curve is defined as the curvature of its osculating circle at each point.
• curve

  A curve (also called a curved line in older texts) is, generally speaking, an object similar to a line but that need not be straight. Thus, a curveis a generalization of a line, in that its curvature need not be zero. A simple example of a curve is the parabola, shown to the right.
• curve fitting

  Curve fitting is the process of constructing a curve, or mathematical function, that has the best fit to a series of data points, possibly subject to constraints
• curve sketching

  To produce an accurate sketch a given function f, consider the following steps.
• curvilinear asymptote

  A curvilinear asymptote is an asymptote that's a curve.
• cycle

  Is defined as a closed trail where no other vertices are repeated apart from the start / end vertex.
• cycloid

  A cycloid is the curve traced by a point on the rim of a circular wheel as the wheel rolls along a straight line without slipping.
• cylinder

  Is a three-dimensional shape with two round shapes at either end and two parallel lines connecting the round ends.
• cylindrical coordinates

  Cylindrical coordinates are a generalization of two-dimensional polar coordinates to three dimensions by superposing a height () axis. Either or is used to refer to the radial coordinate and either or to the azimuthal coordinates.
• cylindrical shell

  A cylindrical shell is a region contained between two cylinders of the. Same height with the same central axis.
• decagon

  A decagon is a ten-sided polygon or 10-gon.
• decay

  Decay refers to the gradual deterioration or decline of a substance, object, system, or organism over time, often resulting from natural processes or the passage of time.
• decimal number

  Decimals are the numbers, which consist of two parts namely, a whole number part and a fractional part separated by a decimal point.
