See Inverse sine function.

Arrow
The notation PQ denoting the directed line segment with initial point P and terminal point Q.

Augmented matrix
A matrix that represents a system of equations.

Bounded above
A function is bounded above if there is a number B such that ƒ(x) ? B for all x in the domain of ƒ.

Constant function (on an interval)
ƒ(x 1) = ƒ(x 2) x for any x1 and x2 (in the interval)

Infinite limit
