- Solving Integrals for e^-ax^2: (i), (ii) (iii) - Physics Forums
The discussion revolves around evaluating integrals of the form \ (\int_ {0}^ {\infty} e^ {-ax^2} x^n dx\) for \ (n = 2, 3, 4\), given the known integral \ (\int_ {0}^ {\infty} e^ {-ax^2} dx = \frac {\sqrt {\pi}} {2\sqrt {a}}\) Participants explore methods such as differentiation with respect to the parameter \ (a\) and integration by parts Participants discuss using differentiation with
- Understanding Integration of 1 (x^2 + a^2) and the Role of the Tan . . .
2) use the substitution , which gives , the indefinite integral you already solved (up to a constant 1 a) Just to be clear, all my integrals here are indefinite integrals
- What is the relationship between the integral and the area of half a . . .
The discussion revolves around the relationship between integrals and the area of geometric shapes, specifically focusing on the area of half a circle and an ellipse Participants explore the implications of certain integrals and their geometric interpretations Exploratory, Conceptual clarification, Mathematical reasoning, Problem interpretation Participants discuss the integral \ (\int
- How can I solve integrals of the form x^n e^ (-x^2) by hand?
Making substitution for x^2 still leaves a factor x in the denominator since u = x^2 implies du = 2 x dx The result then would give a square root of u in the integral, which I cannot solve by integration by parts Is there any way to find an explicit formula for this integral?
- Why the Chern numbers (integral of Chern class) are integers?
One participant provides an example involving the tangent bundle of the 2-sphere to illustrate how the integral of the curvature form relates to the first Chern class and the Euler characteristic
- How do you derive the pV Work formula, W= integralpdV?
This discussion revolves around deriving the pV Work formula, specifically W = ∫pdV, within the context of thermodynamics Participants are exploring the relationship between force, pressure, and work done during a state change Conceptual clarification, Mathematical reasoning, Problem interpretation Participants discuss substituting force in the work equation and the implications of
