Function Tank Tops
Description: A graphic with black background displaying text at the top and a sine wave representation. The text reads "FOR ANYONE LOOKING FOR A SINE" with "SINE" in orange. Below, a speech bubble with "THIS IS IT" points to a waveform with internal vertical lines. The waveform is predominantly white.
Description: Digital layout featuring programming code in white text on a black background. The code includes a function named "repeat()" which loops the commands "eat();", "sleep();", "code++;", "workout++;", "Pray++;", and "repeat();". The code is written in a simple, classic style, commonly used in programming jobs.
Description: A close-up visual of a keyboard with a circuit board pattern overlay. The keys are a standard QWERTY layout with function keys and a numeric keypad on the right. The overall color scheme transitions from pink and purple at the top to green and blue at the bottom, resembling a gradient.
Description: A dark background displays a series of mathematical equations demonstrating the derivative of a function. The steps include rewriting the function with an exponent, applying the chain rule and power rule, and finally arriving at the derivative formula. The text "Power Rule" and "Chain Rule" are also present.
Description: A visual representation of Python code. It displays imported libraries like pandas and numpy, a function 'clean_data' for dataset preprocessing including dropping nulls and converting 'date' to datetime, and a class 'VectorModel' with initialization and optimization methods. The code also includes print statements for data transformation completion and displaying the head of the cleaned data.
Description: A detailed scientific illustration of a circle of radius R with a highlighted chord and central angle θ, ringed by stars, above the chord formula crd θ = 2R sin(θ/2), set against a deep dark background. Hipparchus of Nicaea (c. 190–120 BC) compiled the first known table of chords, the ancestor of the sine function. He also made one of the first star catalogues and discovered the precession of the equinoxes. A gift idea for mathematicians, math teachers and engineers, and a quiet statement piece for a study, classroom or office wall.

Description: A dark background with lines of computer code. Key phrases include "const displayElement =", "let userCount = 1024;", "function processData(input)", "// abstract digital representation", "return input.toUpperCase();", and "processData('Vector Art');". The code is displayed in a monospaced font with different colors for keywords and strings.
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 dark-themed visual representation of programming code with line numbers on the left. At the center, highlighted in white bold text, reads 'It worked on my local'. The code contains various function calls, variable declarations, and comments, with some lines displaying subtle orange and yellow gradients.
Description: A white line diagram on a black background illustrating a control system. It features a summation circle with inputs 'r' and 'e', and outputs 'r', 'e', and 'u'. Two blocks labeled 'C' and 'F' are connected, receiving and sending 'y' signals. Another block labeled 'P' is grounded. Below the diagram, the equation 'H(s) = H(s) / 2' is displayed.
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 features white text stating "MATH PUNS" at the top. Below this is a yellow and white waveform graphic. The next line reads "ARE THE THE" in white. Prominently displayed are the words "FIRST" in white and "SINE" in yellow. The bottom line reads "OF MADNESS" in white. Small tick marks resembling rulers appear on the left and right sides of the design.
Description: A graphic featuring mathematical diagrams of a parabola and a cone. The text reads "MY PARABOLA DON'T WANT NONE" in yellow and white, and "UNLESS YOU GOT CONES HUN" in white and yellow. The parabola is shown on a coordinate plane, and the cone has labeled points and dashed lines.
Description: A dark background displays lines of Python code in various bright colors. Key elements include function definitions like 'def process_data(data):', variable assignments like 'index = "Initialize"[]', and conditional statements like 'if check(item):'. The code appears to be processing data and computing results.
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.
