Integrals: Class 12 Mathematics (Bihar Board) important questions and practice
Integrals is chapter 7 of 13 in Bihar Board Class 12 Mathematics. Below are the topics the paper draws from, the question types that come up again and again, and a free practice test on this chapter alone.
Topics in this chapter
- Integration as the inverse of differentiation; standard integrals
- Integration by substitution
- Integration using partial fractions
- Integration by parts and the e^x[f(x) + f'(x)] form
- Standard integrals of the forms 1/(x^2 + a^2), 1/root(a^2 - x^2), root(x^2 + a^2) etc.
- Definite integrals: fundamental theorem and properties
What examiners usually ask
- Evaluate the integral of (x^2 + 1)/((x - 1)^2 (x + 3)) dx using partial fractions
- Evaluate the integral of e^x (sin x) dx by parts
- Evaluate the definite integral from 0 to pi/2 of (sin x)/(sin x + cos x) dx using properties
Exam tip
Memorise the standard integral table and the property integral from 0 to a of f(x) = integral of f(a - x), which solves most definite integral questions; write 'let x = ...' substitutions clearly and change limits for definite integrals.
