Integration MCQ : Here you will find MCQ Questions related to "Integration" in Matlab. These Integration MCQ Questions Will help you to improve your Matlab knowledge and will prepare you for various Examinations like Competitive Exams, Placements, Interviews and other Entrance Exmaniations.
Question 1
How many different types of Integration there?
A. 1
B. 2
C. 3
D. 4
View Answer
Ans : B
Explanation: Integration deals with two essentially different types of problems : indefinite integral and definite integral.
Question 2
we basically reverse the process of differentiation. This reverse process is known as ?
A. differentiation
B. integration
C. anti-differentiation
D. anti-integration
View Answer
Ans : C
Explanation: we basically reverse the process of differentiation. This reverse process is known as anti-differentiation, or finding the primitive function, or finding an indefinite integral.
Question 3
MATLAB provides an ________ command for calculating integral of an expression
A. integer
B. decimal
C. number
D. int
View Answer
Ans : D
Explanation: MATLAB provides an int command for calculating integral of an expression. To derive an expression for the indefinite integral of a function, we write: int(f);
Question 4
The command quad() cannot do ______ integrals.
A. Definite
B. Indefinite
C. Particular
D. Any
View Answer
Ans : B
Explanation: If we introduce infinity as an argument to our command ‘quad()’, it will result in an error. This is because it will not take Inf as an input limit. It can do definite integral over a finite range.
Question 5
What is the class of the result of quad() command?
A. long
B. short
C. double
D. unsigned
View Answer
Ans : C
Explanation: The class of the result of quad command is double. This is an in-built command in MATLAB and it will give the answer in the format double.
Question 6
The accuracy of quad() is ___________
A. high
B. medium
C. very low
D. low
View Answer
Ans : D
Explanation: The quad() function is pertinent for low accuracy problems. The quadl() function is more useful for high accuracy problems.
Question 7
The answer for indefinite integration in MATLAB is __________
A. The only possible particular integral
B. One of the many possible integrals
C. 0
D. ERROR
View Answer
Ans : B
Explanation: Indefinite integrals can have many possible solutions. Only of the solution is provided by the int() function.
Question 8
The class of the result of an indefinite integration is always _____________
A. signed
B. double
C. array
D. symbolic
View Answer
Ans : D
Explanation: Since we are doing indefinite integration, the result is not a number. It will contain the particular integral after integrating the function and it will only consist of the independent variable. Hence, it’s class will be symbolic.
Question 9
Definite integrals are used for finding area, volume, center of gravity, moment of inertia, work done by a force.
A. TRUE
B. FALSE
C. Can be true or false
D. Can not say
View Answer
Ans : A
Explanation: Definite integrals are used for finding area, volume, center of gravity, moment of inertia, work done by a force, and in numerous other applications.
Question 10
Indefinite integral is unique.
A. TRUE
B. FALSE
C. Can be true or false
D. Can not say
View Answer
Ans : B
Explanation: Indefinite integral is not unique, because derivative of x2 + c, for any value of a constant c, will also be 2x.
