- 1/3
- 1/4
- 1
Show answer and solution
Correct answer: B. 1/3
∫₀¹ x² dx = [x³/3]₀¹ = 1/3 - 0 = 1/3. (Area under parabola from 0 to 1.)

Worked practice questions
∫ ln x dx (by parts: u = ln x, dv = dx):
- ln x / x
- x ln x - x + C
- x ln x
- ln²x
Show answer and solution
Correct answer: B. x ln x - x + C
u = ln x, du = dx/x; dv = dx, v = x.
We have ∫ ln x dx = x ln x - ∫ x × (1/x).
So dx = x ln x - x + C.
∫ from -a to a (odd function) dx =
- f(a) - f(-a)
- 0 (odd function symmetric about origin)
- 2 × ∫ from 0 to a
- ∞
Show answer and solution
Correct answer: B. 0 (odd function symmetric about origin)
For odd function (f(-x) = -f(x)): ∫_(-a)^a f(x) dx = 0. (Negative half cancels positive half.) For even functions (f(-x) = f(x)): ∫_(-a)^a = 2 × ∫_0^a.
