Multivariable calculus is defined as the extension of calculus in 1 variable to calculus with function of several variables: the differentiation and integration of functions involving multiple variables, rather than just 1. If you think you are a great mathematician, take a chance and complete out small quiz.

### What is the advantage that comes with multivariable calculus?

• A.

They yield many counter-intuitive results not demonstrated by single-variable function.

• B.

They yield many results not demonstrated by single-variable function.

• C.

They yield many counter-intuitive results not demonstrated by the f(x) function.

• D.

They reveal many counter-intuitive results not demonstrated by single-variable function.

A. They yield many counter-intuitive results not demonstrated by single-variable function.
Explanation
Multivariable calculus offers the advantage of revealing many counter-intuitive results that cannot be demonstrated by single-variable functions. This means that by considering multiple variables and their interactions, multivariable calculus allows for a deeper understanding of complex systems and phenomena. It enables the exploration of relationships and patterns that may not be apparent when only considering a single variable.

### What are the main points of study in multivariable calculus?

• A.

Continuity

• B.

Limits

• C.

Limits and continuity.

• D.

F(x)

C. Limits and continuity.
Explanation
The main points of study in multivariable calculus are limits and continuity. This involves understanding the behavior of functions as they approach certain values or points, and ensuring that the function is continuous, meaning that there are no abrupt changes or breaks in the function's graph. By studying limits and continuity, mathematicians can analyze the behavior of functions in multiple dimensions and solve complex problems involving multiple variables.

### How can "limits" in derivatives' study be defined?

• A.

They are the fundamental concepts in calculus and analysis concerning the behavior of that function.

• B.

They are the fundamental concepts in calculus and analysis concerning the behavior of that function near a particular input.

• C.

They are the fundamental concepts concerning the behavior of that function near a particular input.

• D.

They are the fundamental concepts in calculus and analysis concerning a function near a particular input.

B. They are the fundamental concepts in calculus and analysis concerning the behavior of that function near a particular input.
Explanation
This answer correctly defines "limits" in derivatives' study as the fundamental concepts in calculus and analysis concerning the behavior of that function near a particular input. It emphasizes the importance of understanding how a function behaves in the vicinity of a specific input value, which is crucial in studying derivatives.

### How can a continuous function be defined?

• A.

It is a function for which sufficiently small changes in the input result in small changes in the output.

• B.

It is a function for which sufficiently great changes in the input result in arbitrarily small changes in the output.

• C.

It is a function for which sufficiently small changes in the input result in arbitrarily small changes in the input.

• D.

It is a function for which sufficiently small changes in the input result in arbitrarily small changes in the output.

D. It is a function for which sufficiently small changes in the input result in arbitrarily small changes in the output.
Explanation
A continuous function is defined as a function where sufficiently small changes in the input will result in arbitrarily small changes in the output. This means that as the input values get closer and closer together, the corresponding output values will also get closer and closer together. This property of a continuous function allows for smooth and predictable behavior, as even tiny changes in the input will not cause drastic or unexpected changes in the output.

### What is a parabola?

• A.

It is a plane curve which is mirror-symmetrical , and is approximately U-shaped when oriented.

• B.

It is a plane curve which is approximately U-shaped when oriented.

• C.

It is a plane curve which is mirror-symmetrical , and is approximately C-shaped when oriented.

• D.

It is a plane curve which is mirror-symmetrical , and is approximately U-shaped.

A. It is a plane curve which is mirror-symmetrical , and is approximately U-shaped when oriented.
Explanation
A parabola is a plane curve that is mirror-symmetrical, meaning that it has a line of symmetry. It is also approximately U-shaped when oriented, with the vertex being the lowest or highest point on the curve depending on the orientation.

### What is a partial differentiation?

• A.

It generalizes the notion of the derivative to higher dimensions.

• B.

It generalizes the notion of the derivative to lower dimensions.

• C.

It generalizes the derivative to higher dimensions.

• D.

It generalizes the derivative to lower dimensions.

A. It generalizes the notion of the derivative to higher dimensions.
Explanation
Partial differentiation is a mathematical concept that extends the idea of taking derivatives to functions with multiple variables. It allows us to find the rate of change of a function with respect to one variable while treating all other variables as constants. This generalization is particularly useful in multivariable calculus and is essential for solving problems involving functions of more than one variable.

### What is the Lagrange multiplier?

• A.

It is a strategy for finding the local maxima and minima of a function subject to equality constraints.

• B.

It is a strategy for finding the local minima of a function subject to equality constraints.

• C.

It is a strategy for finding the local maxima of a function subject to equality constraints.

• D.

It is a strategy for finding the local limits of a function subject to equality constraints.

A. It is a strategy for finding the local maxima and minima of a function subject to equality constraints.
Explanation
The Lagrange multiplier is a strategy that is used to find the local maxima and minima of a function while considering equality constraints. It helps in optimizing a function by incorporating the constraints into the optimization process. By introducing Lagrange multipliers, the function can be modified to include the constraints as additional terms, allowing for the identification of the optimal values that satisfy both the objective function and the constraints.
