# CALCULUS GLOSSARY

Mr. X is glad to provide video presentations of hundreds of calculus glossary terms. The calculus glossary is part of a complete math glossary available free of charge on the website. All calculus glossary terms are provided free of charge to all users.
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.
Upper-case 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.
