The Gaussian integral is a fundamental result in mathematics, especially in probability and physics. It evaluates the integral of the exponential function with a negative square exponent over the entire real line. Surprisingly, the result is the square root of π, even though the function itself has no elementary antiderivative. This elegant outcome plays a central role in the normal distribution and in solving problems involving heat, diffusion, and quantum mechanics. 📌Support us - Like/Share/F
