See Sinusoid.

• Arcsine function

See Inverse sine function.

• Augmented matrix

A matrix that represents a system of equations.

• Causation

A relationship between two variables in which the values of the response variable are directly affected by the values of the explanatory variable

• End behavior

The behavior of a graph of a function as.

• Extraneous solution

Any solution of the resulting equation that is not a solution of the original equation.

• Linear combination of vectors u and v

An expression au + bv , where a and b are real numbers

• Logarithmic re-expression of data

Transformation of a data set involving the natural logarithm: exponential regression, natural logarithmic regression, power regression

• Newtonâ€™s law of cooling

T1t2 = Tm + 1T0 - Tm2e-kt

• Order of magnitude (of n)

log n.

• Pythagorean

Theorem In a right triangle with sides a and b and hypotenuse c, c2 = a2 + b2

The graph in three dimensions of a seconddegree equation in three variables.

The measure of an angle in radians, or, for a central angle, the ratio of the length of the intercepted arc tothe radius of the circle.
