Integral Equation Phone Cases - iPhone and Android
Description: A mathematical equation presented in white text on a black background. The equation features a definite integral from infinity to 0 of a fraction: 0 times x to the power of s-1 times limit over the square root of e to the power of x minus 1 plus dx. This is equated to zeta(s) multiplied by Gamma(s).
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 monochrome text-based representation of the Fourier transform formula. The top line reads 'Fourier transform' in a bold, sans-serif font. Below, the mathematical equation F(\xi) = \int_{-\infty}^{\infty} f(x)e^{-i2\pi x\xi} dx is displayed.

Description: A black background with white text and a white stick figure. The text reads "I STOPPED UNDERSTANDING MATH WHEN THE ALPHABET DECIDED TO GET INVOLVES". Below the text, a confused stick figure is shown with question marks above its head. To the right of the stick figure is a mathematical equation: "∫ from 0 to x = A² ∫ cos(p²) dp".
Description: A black cat with yellow eyes sits next to a golden, ornate trophy. The background is black and features white chalk-like mathematical equations and formulas, including "Projectile", "F = G^2 / S = 2", and integral notations. The text "What cats really th" is visible at the top.
Description: A vertical composition resembling a Christmas tree made of chalk-drawn mathematical formulas and symbols on a black background. At the top, an atom symbol serves as the tree topper. Various equations, integrals, graphs, and snowflakes fill the shape of the tree. Text includes mathematical notation and symbols.
Description: A humorous and educational composition featuring a cute cartoon penguin wearing glasses and a bow tie. The background is filled with various mathematical formulas and symbols, including equations like E=mc², integral functions, quadratic formula, and geometric shapes. The phrase "I DO THE MATH THE CUTE WAY" is prominently displayed at the bottom.
Description: A humorous graphic depicting two green chameleons on branches. Mathematical equations involving integrals and variables 'x', 'y', and 't' are displayed. One integral segment is labeled '30' and 'xd', while the lower equations show 'integral from xt to t = x(t)' and 'integral from yt to t = y(t)'.
Description: A dark background displays two green chameleons perched on brown branches. A red, swirled symbol resembling an integral is placed between them. Below the chameleons are two mathematical equations: 'x(t) = a \int_{0}^{t} sin (\frac{u^{n+1}}{n+1}) du' and 'y(t) = a \int_{0}^{t} cos (\frac{u^{n+1}}{n+1}) du'.
Description: A stick figure stands with a confused expression and hand on head, surrounded by question marks. To the right, complex mathematical equations including an integral, summation, and limit are displayed prominently. The background is black, and all visual elements and text are white.
Description: A black background with white mathematical equations arranged in a circular pattern resembling a clock face. White clock hands are positioned at the center. Equations include "x² + y² = z²", "lim (1/x)", "∫ e^x dx", "f(x) = mx + c", "d/dx sin(x)", "e^(iπ) + 1 = 0", "log10(100)", "2³ - 1", "√(16+2)", "(3+2)²", "√144", "Σ n/n!", and "π ≈ 3.14159".
Description: A black background filled with colorful math symbols and text. The text reads: 'I WAS GOING TO TELL A PRE-CALCULUS JOKE, BUT IT HAD TOO MANY LIMITS. AND THE DERIVATIVE JOKE FEELS A BIT REPETITIVE. SO I'LL SUM IT UP WITHOUT THE COMPLEXITY!'. Various mathematical operators and symbols are interspersed throughout the text.
