Class 12 Integration: Important Questions Board Exam 2025 Part 5

Class 12 Maths Integration: Important Questions for Board Exam 2025 Part 5 Solution Step by Step Maths Doubt Clear.
*Introduction*
Integration, a fundamental concept in calculus, is the reverse process of differentiation. It involves finding the antiderivative of a function, which is a function whose derivative is the original function. In Class 12 Maths, integration is a crucial topic with various applications in real-world problems.
*Key Topics to Cover*
1. *Indefinite Integration:*
Integration of standard functions (polynomial, trigonometric, exponential, logarithmic)
Integration by substitution
Integration by parts
Integration using trigonometric identities
2. *Definite Integration:*
Fundamental theorem of calculus
Definite integration of standard functions
Definite integration by substitution
Definite integration by parts
Properties of definite integrals
Applications of definite integrals (area under a curve, average value of a function)
*Important Questions*
*Indefinite Integration*
1. Integrate the following functions:
x^3 + 2x^2 - 5
sin(2x) + cos(x)
e^x + ln(x)
1/x^2 + 1/(x+1)
2. Integrate the following functions using substitution:
√(1-x^2)
1/(x^2 + 4)
e^x * sin(x)
3. Integrate the following functions using integration by parts:
x * e^x
x * ln(x)
sin(x) * e^x
*Definite Integration*
1. Evaluate the following definite integrals:
∫(x^2 + 1) dx from 0 to 2
∫(sin(x) + cos(x)) dx from 0 to π/2
∫(e^x + 1/x) dx from 1 to e
2. Evaluate the following definite integrals using substitution:
∫√(4-x^2) dx from 0 to 2
∫(x^2 + 1)/(x^4 + 1) dx from 0 to 1
3. Evaluate the following definite integrals using integration by parts:
∫x * e^x dx from 0 to 1
∫x * ln(x) dx from 1 to e
*Applications of Definite Integrals*
1. Find the area under the curve y = x^2 from x = 0 to x = 2.
2. Find the average value of the function f(x) = sin(x) over the interval [0, π].
3. Find the volume of the solid of revolution obtained by rotating the region bounded by y = x^2 and y = 4 about the x-axis.
*Tips for Solving Integration Problems*
Practice regularly to improve your integration skills.
Understand the different methods of integration and when to use them.
Use trigonometric identities and algebraic manipulation to simplify integrands.
Check your answers by differentiating the result.
