  • What is the Integral of 2^ (x)? - Physics Forums
    Could someone please help me with the integral of 2^x dx I bet its really simple but i have looked in several books and they just give the answer
  • Prove that the integral is equal to ##\pi^2 8## - Physics Forums
    Does it convince you? I can't understand how they derived equation ## (3)## from equation ## (2)## Sadly, there's no context Where did this integral arise? What motivated the specific change of variables? What characterizes the class of similar integrals solved by this method? From what's presented, it seems it's "guess and check"
  • Can the Volume of a Sphere be Calculated by . . . - Physics Forums
    The the area integral is a double integral over r and the azimuthal angle The volume integral is over r, the azimuthal angle and the polar angle You're missing some parts of the "big picture" about spherical coordinates You kind of skipped the intergrating over the azimuthal angle part by including 2 \pi straight into your integrand
  • How can I solve integrals of the form x^n e^ (-x^2) by hand?
    Integrals of the form ∫ x^n e^ (-x^2) dx can be challenging, especially for quantum mechanics calculations For n=2, the integral can be computed using integration by parts, leading to a closed form solution of √π 2 When n is odd, the integrand becomes odd, resulting in the integral evaluating to zero due to symmetry Higher powers can be simplified by reducing the power through
  • Integral of 1 (x^2 + 2) dx - 2) dx ? • Physics Forums
    The integral of 1 (x^2 + 2) dx can be approached using trigonometric substitution, as it resembles the standard integral form for arctangent A common substitution is x = √2 * tan (θ), which simplifies the integral to a form that allows for straightforward integration
  • What is the Integral of -e^ (-x)? - Physics Forums
    The integral of -e^ (-x) is derived using u-substitution, where u = -x, leading to the result -e^ (-x) + C The negative sign arises because the derivative of -x is -1, thus requiring division by -1 during integration The discussion emphasizes that integration can be viewed as the reverse of differentiation, which simplifies the process Some participants clarify that the method of
  • How to Integrate [1 (x^2 + 1)] dx? • Physics Forums
    The integral of 1 (x^2 + 1) dx can be solved using the direct formula, yielding arctan (x) + C Substitution methods were discussed, including u = x^2 + 1 and trigonometric substitution with x = tan (θ), but these approaches led to complications with the variable x remaining in the equation Some participants suggested that recognizing the integral as a standard form could simplify the
  • How can the formula for integrating 1 (x^2+y^2)^(3 2) be derived?
    The discussion focuses on deriving the integral of 1 (x^2+y^2)^ (3 2), emphasizing the need for a clear understanding of the derivation process rather than just the formula A suggested approach involves using trigonometric substitution, specifically x = y*tan (θ), which simplifies the integral significantly Participants highlight that many integration formulas arise from initial
