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.
An echocardiogram (echo) uses ultrasound to create pictures of your heartâs movement. A transesophageal echo (TEE) test is a type of echo that uses a long, thin, tube (endoscope) to guide the ultrasound transducer down the esophagus (âfood pipeâ that goes from the mouth to the stomach).This lets the doctor see pictures of the heart without the ribs or lungs getting in the way. transesophageal echo (TEE) test is a type of echo that uses a long, thin, tube (endoscope) to guide the ultrasound transducer down the esophagus (âfood pipeâ that goes from the mouth to the stomach).
