Title  Description  

Definite Integral  An integral evaluated between limits of integration is termed a Definite Integral.  
Delta  Delta is the fourth letter of the Greek alphabet. Uppercase Delta looks like a triangle and is used to mean "the change in..." 

Derivative  A first Derivative is the slope of the line tangent to a function. A Derivative provides an instantaneous rate of change between variables. 

Differentiable  If a function is smooth and continuous it is differentiable.  
Differential Equation  A Differential Equation employs derivatives and algebra to solve for variables that represent functions.  
Discontinuity  When a function is literally not continuous because of a gap, a step, a hole, or any kind of "break" it is considered discontinuous.  
Dot Product  A product of vector multiplication, the Dot Product is a scalar, which means it has magnitude only and not an associated direction. The Dot Product does not result in another vector.
