Worked practice questions

The integral $\int x^3\, dx$ equals:

  1. $3x^2 + C$, the derivative of $x^3$ instead on chart
  2. $x^3 + C$, missing the power-up rule on chart entirely
  3. $x^4/4 + C$, by power rule for integration of $x^n$
  4. $4x^4 + C$, the wrong scaling factor on the chart here
Show answer and solution

Correct answer: C. $x^4/4 + C$, by power rule for integration of $x^n$

$\int x^n\, dx = x^{n+1}/(n+1) + C$ gives $x^4/4 + C$.

To evaluate $\int x\cos x\, dx$, the best technique is:

  1. Direct substitution $u = \cos x$ on the chart at one step
  2. Partial fractions, since the integrand is a rational function
  3. Trigonometric identity simplification on the school chart
  4. Integration by parts with $u = x$, $dv = \cos x\, dx$
Show answer and solution

Correct answer: D. Integration by parts with $u = x$, $dv = \cos x\, dx$

Integration by parts: $u = x$, $dv = \cos x\, dx$ gives $du = dx$, $v = \sin x$ result $x\sin x + \cos x + C$.

Compute ∫ 2x sin(x²) dx using substitution:

  1. $\sin(x^2) + C$
  2. $\cos(x^2) + C$
  3. $-\cos(x^2) + C$
  4. $x^2 \cos(x^2) + C$
Show answer and solution

Correct answer: C. $-\cos(x^2) + C$

Let u = x², du = 2x dx → ∫sin(u) du = -cos(u) + C = -cos(x²) + C. Substitution exploits the chain rule in reverse.
