Math Problem Statement

Evaluate the integral ∫ (1 / √(3 - x^2)) dx. Use a capital C to denote an arbitrary constant of integration.

Solution

The given integral is:

13x2dx\int \frac{1}{\sqrt{3 - x^2}} \, dx

This integral looks similar to the standard form for arcsine, which is:

1a2x2dx=arcsin(xa)+C\int \frac{1}{\sqrt{a^2 - x^2}} \, dx = \arcsin\left(\frac{x}{a}\right) + C

Here, a2=3a^2 = 3, so a=3a = \sqrt{3}.

Thus, applying this formula, the solution to the integral is:

arcsin(x3)+C\arcsin\left(\frac{x}{\sqrt{3}}\right) + C

Where CC is the constant of integration.

Would you like further clarification on any part of this solution? Here are some related questions for practice:

  1. How do you integrate 14x2dx\int \frac{1}{\sqrt{4 - x^2}} \, dx?
  2. What is the derivative of arcsin(xa)\arcsin\left(\frac{x}{a}\right)?
  3. How would the integral change if the expression was 19x2dx\int \frac{1}{\sqrt{9 - x^2}} \, dx?
  4. How do you recognize integrals that follow the arcsine pattern?
  5. What happens if the integrand is 1a2+x2\frac{1}{\sqrt{a^2 + x^2}} instead?

Tip: When integrating expressions involving square roots like a2x2\sqrt{a^2 - x^2}, it's helpful to memorize standard integral forms like arcsine or arctangent functions.
