Pi Mathematica | Math Simplified on Instagram: "The Dirac delta function is absolutely one of the most delightfully bizarre creatures in mathematics. The Dirac delta isn’t actually a function in the usual sense—it’s zero everywhere except at one point, where it’s infinitely concentrated and you cant graph it like a normal function. That spike at x = 0 is just a visual metaphor. Its true meaning lies in how it interacts with other functions under integration. Credit: physicswithelliot / YT #dirac
