Which statement best describes the meanings of definite and indefinite integrals?
Correct Answer
C. Definite integrals represent areas under curves while indefinite integrals represent families of antiderivatives.
Explanation
Definite integrals represent the calculation of the area under a curve over a specific interval. This means that it gives a precise value for the area. On the other hand, indefinite integrals represent families of antiderivatives. This means that it gives a general formula that represents all possible antiderivatives of a function. The indefinite integral does not give a specific value, but rather a set of functions that can be obtained by adding a constant of integration.

Which two scientists were involved in the discovery of "the Fundamental Theorem of Calculus?"
Correct Answer(s)
A. Sir Isaac Newton
C. Gottfried Wilhelm Leibniz
Explanation
Sir Isaac Newton and Gottfried Wilhelm Leibniz were both involved in the discovery of "the Fundamental Theorem of Calculus". Newton developed the concept of calculus independently and introduced the fundamental concepts of differentiation and integration. Leibniz, on the other hand, also developed calculus independently and introduced the concept of the integral sign and the notation used in calculus. Both of their contributions were crucial in the development of calculus and the formulation of the Fundamental Theorem of Calculus.
3.
Who introduced the notation for the indefinite integral?
Correct Answer
C. Gottfried Leibniz
Explanation
Gottfried Leibniz is credited with introducing the notation for the indefinite integral. He developed a system of symbols that are still used today, including the integral sign (âˆ«) and the differential notation (dx). This notation revolutionized the field of calculus and made it easier to express and manipulate mathematical concepts involving integrals. Leibniz's notation is widely used and recognized as the standard way to represent the indefinite integral in mathematics.
4.
Which method is used to find integration by introducing an independent variable?
Correct Answer
A. Integration by Substitution
Explanation
Integration by substitution is a method used to find integration by introducing an independent variable. This technique involves substituting a new variable in place of the original variable in the integral, which helps simplify the integrand and make the integration process easier. By choosing an appropriate substitution, the integral can be transformed into a more manageable form, allowing for easier evaluation.
5.
Which method involves ILATE rule?
Correct Answer
B. Integration by Parts
Explanation
Integration by Parts is the method that involves the ILATE rule. The ILATE rule is a mnemonic device used to determine which functions to choose as u and dv when applying the integration by parts formula. It stands for Inverse trigonometric, Logarithmic, Algebraic, Trigonometric, and Exponential functions. By choosing u and dv appropriately according to this rule, integration by parts becomes more efficient and easier to solve.
6.
If any integrand have trigonometric functions, then Trigonometric Identities method is used.
Correct Answer
A. True
Explanation
The explanation for the correct answer is that when an integrand contains trigonometric functions, it is often necessary to use trigonometric identities to simplify the expression before integrating. These identities allow us to rewrite the trigonometric functions in terms of other trigonometric functions or constants, making the integration process easier. Therefore, it is true that the Trigonometric Identities method is used when dealing with integrands that involve trigonometric functions.
7.
Partial fraction method is used when the ration of two polynomials is there.
Correct Answer
A. True
Explanation
The explanation for the given correct answer is that the partial fraction method is indeed used when there is a ratio of two polynomials. This method involves breaking down a rational function into simpler fractions with denominators that are irreducible polynomials. By decomposing the rational function into partial fractions, it becomes easier to integrate or manipulate the function algebraically. Therefore, the statement "Partial fraction method is used when the ratio of two polynomials is there" is true.
8.
There are 3 forms of partial fraction.
Correct Answer
B. False
Explanation
The statement "There are 3 forms of partial fraction" is false. In fact, there is only one form of partial fraction decomposition, which involves breaking down a rational function into a sum of simpler fractions. The process involves finding the partial fractions with distinct linear factors and irreducible quadratic factors in the denominator. Therefore, the correct answer is false.
9.
The forms of partial fraction
Correct Answer(s)
B. Proper
D. Improper
Explanation
The forms of partial fraction decomposition include proper and improper fractions. A proper fraction has a numerator of lower degree than the denominator, while an improper fraction has a numerator of equal or higher degree than the denominator. In the context of partial fraction decomposition, proper fractions can be further decomposed into simpler fractions, while improper fractions require additional steps such as polynomial long division before decomposition can be performed. Therefore, the given answer of "Proper, Improper" correctly identifies the two forms of partial fractions.
