Cheat Sheet
- Fundamental Theorem of Calculus -
When tackling questions about integration, master the Fundamental Theorem of Calculus that links definite integrals and antiderivatives. In Part 1, F(x)=∫_a^x f(t)dt shows how differentiation reverses integration, while Part 2 gives ∫_a^b f′(x)dx=f(b)−f(a), letting you compute areas directly (Source: MIT OpenCourseWare). This tool is crucial on any integration problems quiz or integral calculus questions.
- u-Substitution Technique -
u-Substitution is your go-to method for integrals where a composite function appears; set u equal to an inner function so du matches f ′(x)dx. For instance, ∫2x·cos(x^2+1)dx becomes ∫cos(u)du, yielding sin(u)+C (u=x^2+1). Practicing this on definite integral practice ensures you spot substitutions quickly.
- Integration by Parts and LIATE -
Integration by parts comes from ∫u dv = u·v − ∫v du, and the LIATE mnemonic (Logs, Inverse trig, Algebraic, Trig, Exponential) helps choose u. For example, ∫x e^x dx = x e^x − ∫1·e^x dx = x e^x − e^x + C (Stewart's Calculus). This technique tackles tougher integral calculus questions and boosts your confidence on tricky integrals.
- Area and Volume Applications -
Translating integrals into geometrical quantities is key: area under y=f(x) is ∫_a^b f(x)dx, while revolving around the x-axis gives volume V=π∫_a^b[f(x)]^2dx (Source: University of Cambridge). The washer method handles holes, and the shell method uses 2π∫ x·f(x)dx for cylindrical shells. Visualizing these setups turns abstract formulas into concrete problem-solving tools.
- Numerical Integration Methods -
When antiderivatives are elusive in an integration techniques test, use numerical rules like Trapezoidal and Simpson's. Simpson's Rule, for instance, approximates ∫_a^b f(x)dx ≈ (Δx/3)[f(x_0)+4f(x_1)+f(x_2)] over each interval (Khan Academy). Regular practice on integration problems quizzes sharpens your error estimates and computational accuracy.
