When you graph, don't try to plot loads of points. Note that the cosine is at y = 1 when x = 0 and 2Ï; at y = 0 for x = Ï/2 and 3Ï/2, and at y = â1 for x = Ï. Plot these five interesting points, and then fill in the curve.
Transesophageal echocardiogram. A transesophageal echocardiogram, or TEE (TOE in the United Kingdom, reflecting the spelling transoesophageal), is an alternative way to perform an echocardiogram. A specialized probe containing an ultrasound transducer at its tip is passed into the patient's esophagus.
TEE (Trans-Esophageal Echocardiogram) The TEE test takes a detailed picture of your heart and its major blood vessels. This test helps to detect heart valve disease, heart tumors, and blood clots inside the heart. It also helps detect an aneurysm (AN-your-izm), which is a swelling, like a balloon, in a blood vessel. TEE stands for trans-esophageal (trans-ee-SOFF-uh-jee-ul) echocardiogram (ek-oh-CAR-dee-oh-gram).
