FAQs on Integral Calculus Mock Test 2025-26 for JEE Main Preparation
1. What is the Integral Test in calculus?
The Integral Test is a mathematical method used to determine the convergence or divergence of infinite series whose terms correspond to a continuous, positive, decreasing function. If the integral of the function from 1 to infinity converges, then the series converges; if the integral diverges, then the series also diverges.
2. How do you apply the Integral Test to a series?
To apply the Integral Test:
1. Verify that the series’ underlying function is continuous, positive, and decreasing for all values n ≥ 1.
2. Replace the general term an with its corresponding function f(x).
3. Evaluate the improper integral ∫1∞ f(x) dx.
4. The series Σan converges if and only if the improper integral converges.
3. Give an example of the Integral Test on a p-series.
Consider the p-series Σn=1∞ 1/np. Using the Integral Test, evaluate ∫1∞ 1/xp dx. The integral converges if p > 1, so the series converges in this case, and it diverges for p ≤ 1.
4. What are the limitations of the Integral Test?
The Integral Test only applies when the function is continuous, positive, and decreasing for all n ≥ 1. If these conditions are not met, the test cannot be used to determine convergence or divergence.
5. How do you determine if the function in the series is decreasing?
To check if a function is decreasing, you can:
- Examine if f(n+1) < f(n) for all n.
- Check if the first derivative f'(x) < 0 for x ≥ 1.
This confirms the function is decreasing on [1, ∞].
6. Why is the Integral Test important in calculus?
The Integral Test is crucial for analyzing the behavior of infinite series, especially for those not easily handled by simpler comparison tests. It provides a connection between definite integrals and series, deepening understanding of both concepts.
7. Can the Integral Test be used for alternating series?
Typically, the Integral Test is designed for series with positive terms. For alternating series, other tests like the Alternating Series Test or Absolute Convergence Test are more suitable.
8. What other tests can be used if the Integral Test conditions are not met?
When the Integral Test cannot be applied, you can use other convergence tests such as the Comparison Test, Limit Comparison Test, Ratio Test, or Root Test, depending on the series structure.
9. List the steps to solve a definite integral using substitution.
The steps to solve a definite integral using substitution are:
1. Identify an inner function whose derivative exists within the integrand.
2. Let u = inner function.
3. Replace all x terms with u.
4. Change the limits of integration to match the new variable.
5. Integrate with respect to u.
6. Substitute back the original variable if needed.
10. What is an improper integral and how is it evaluated?
An improper integral occurs when the interval of integration is infinite or the function is unbounded within the interval. To evaluate, replace the problematic bound with a limit and solve the limit of the definite integral as the variable approaches infinity or the point of discontinuity.
11. Are there any real-world applications of the Integral Test?
Yes, the Integral Test can be used in fields such as physics, engineering, and computer science to analyze long-term growth, decay, or behavior of quantities modeled by infinite series, such as calculating total resistance or evaluating infinite sums in algorithms.
12. What is the difference between definite and indefinite integrals?
A definite integral calculates the area under a curve between two specific points and produces a numerical value, while an indefinite integral represents a family of functions (antiderivatives) and includes a constant of integration.
