Integral Symbol Pins and Buttons
Description: A black background displays a mathematical equation in white text and symbols. The equation begins with an integral symbol from 'n' to 'f', followed by '1', a summation symbol, '(', 'x', '=', and a square root symbol over a summation symbol, followed by ',', '(', 'x', ')', ')'. The words 'Fourier transform' are displayed prominently at the top.
Description: A simple black background with a solid red heart icon at the top. Below the heart, a mathematical integral expression is displayed in white text: the integral from -0 to infinity of 1 divided by x squared plus 1, followed by dx. The expression uses standard mathematical notation.
Description: A bold red heart symbol is placed to the left of a mathematical expression on a black background. The expression is enclosed in square brackets, reads "2 * Integral from 0 to infinity of e^(-x^2) dx", and is squared.
