Trigonometric Functions in my Heart
Students will learn that trigonometric functions can model how their hearts work and can provide also important information about their cardiovascular condition. Students will analyze their own Photplethysmographic heart pulses (PPG) obtained from a fingertip pulse-oximeter.

Using a Graphic User Interface (GUI) developed in MS-Excel, students can visual and manually fit a linear combination of sine functions to their PPG data. Once obtained the best possible fit, students can use the GUI to determine important information about their hearts, like cardiac period and pulse interval, among other.

Advanced students with Calculus background can use the GUI to analyze the first and second derivatives of the PPG pulse, and determine additional cardiovascular information, like vascular aging and arterial stiffness
