Show your students that algebra and trigonometry can be close to their heart. These are .gif images of Valentines drawn from Math Equations. The equation for each heart is written at the top of the Valentines. There are six different equations that produce a heart shape. Some of the Valentines have been drawn as Fractals. The images have a transparent background, so they can be drawn on top of text or other pictures in a Word document. Black and white versions are included so they can be

These 10 math valentines are GIF images of hearts produced on the computer using polar coordinates. The equation used to generate the hearts is written at the top of each valentine. The background is transparent, so the pictures can be printed on colored paper or in documents allowing the background to show through. Use them on documents that you hand out to the students, or let the students place the images on paper and make their own valentines. Although the Valentines can be used by child

A 1-page handout showing the math equation for drawing a 3-leaf and 4-leaf shamrock using polar coordinates. A graph of the equation using the Cartesian Coordinate System is included for comparison of the two coordinate systems. Students can use the equations in Excel, a graphing calculator, or other software and play around with the formulas. Instructions are not included.
