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.
A transesophageal echo (TEE) test is a type of echo test in which the ultrasound transducer, positioned on an endoscope, is guided down the patient's throat into the esophagus (the food pipe leading from the mouth into the stomach). An endoscope is a long, thin, flexible instrument that is about Â½ inch in diameter. transesophageal echo (TEE) test is a type of echo test in which the ultrasound transducer, positioned on an endoscope, is guided down the patient's throat into the esophagus (the food pipe leading from the mouth into the stomach).
