Description: Remember your trigonometric identity: sin^2 x + cos^2 x = 1

Description: Could be considered the most complex of the eight, with five families of equations put to work. The results have a simplicity, suggesting tiles or mosaic.

Description: Clean and rhythmic - waves lock into regular interference that has an almost woven quality. A familiar spiral, but with an extra twist.

Description: Luxuriously opulent, yet fairly sparse, this design creates a strong sense of directionality and flow. This one especially rewards viewing from different distances.

Description: This funny sine cosine tangent pun design is perfect for math nerds who loves math jokes and puns. It can be also given as a birthday or Christmas gift to your boyfriend, girlfriend, wife, husband, relative, best friend, or coworker who also loves math jokes and puns. This design is also fitting in time for International Day of Mathematics (March 14) and World Math Day (March 23).

Description: This awesome, stylish shirt features a graph of periodic trigonometric functions and the words "I Can't Function Without Math". Perfect Tshirt for mathematicians, students of trigonometry, algebra, calculus, math lovers, and math teachers or educators. Are you into Math and Science? Makes a great gift for any mathematician, geek, nerd, tech lover, college student, teacher, or back to school. Funny math pun shirt that includes a graph of periodic trigonometric functions and a clever, sarcastic pun.

Description: A funny trigonometry graphic featuring sine and cosine waves with the message “I Wear This Shirt Periodically.” Perfect for math students and STEM fans.

Description: the math ain't mathin' show your work

Description: The Nerdy Geek Design Unit Circle with Pi Sinus Cosinus for Kids Style and a Formula Sheet is funny for Physics Science Teachers or Professors geometry Students and Circle Trigonometry Scholars. For exam cheat or lesson with your favourite tutor educator.

Description: A complex plane diagram showing the real and imaginary axes with a unit circle. Text labels indicate 'Re', 'Im', 'cos 0', 'sin 0', '1', '0', 'σ', and 'i'. An equation 'e^(iπ) + 1 = 0' is displayed prominently below the diagram, and another equation 'e^(iπ) – cos 0 + i sin 0' is at the top. The style is monochrome and geometric.

Description: A white right triangle is shown at the top with a degree symbol indicating a 90-degree angle. Below it, three lines of text in white script read: 'without you = cos 90°', 'me and you = sin 90°', and 'beside you = tan 90°'. The background is black.

Description: A simple white line drawing of a right triangle with a square symbol indicating the right angle. Below the triangle, in a stylized script font, are three equations: "without you = cos 90°", "me and you = sin 90°", and "beside you = tan 90°". The text is white with a faint pink outline.

Description: A white right triangle with a square symbol in the corner is displayed on a black background. Below the triangle, white text in a script font reads 'without you = cos 90°', 'me and you = sin 90°', and 'beside you = tan 90°'.

Description: The Cosine In Heat logo with the island of St. Thomas

Description: the definition of cosine, using complex numbers, complex exponential

Description: A way of pulling sine waves out of a complex addition of lots of different sine waves with different frequencies, amplitudes, and offsets ( using this fast algorithm called the FFT )
