By doctorj, on July 7th, 2008% This is not a rigorous post in trigonometry but a basic introduction to what trigonometry is and how it’s used. First review the short video below on the mnemonic SOH CAH TOA and then I’ll highlight some applications on trigonometry: One use of trigonometry is to find distances by measuring angles. When the object’s height or [...] . . . → Read More: Trigonometry and What the Heck is SOH CAH TOA?
