A story published Sunday on a Sacred Heart Academy teacher who uses a special “Fab Five” method to teach trigonometry misspelled the word "mnemonic" as "pneumonic." SOHCAHTOA is a mnemonic device that helps students remember the ratios for trig functions. The letters stand for how the angles relate to each other.

Mnemonic is defined by Merriam-Webster as assisting or intended to assist memory. Pneumonic is defined as of, relating to, or affecting the lungs.
