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 echocardiogram (TEE) is a diagnostic procedure that uses echocardiography to assess the heartâs function. Echocardiography is a procedure used to assess the heart's function and structures.EE may be used during surgery to assess the cardiac status of patients with known cardiac disease who are undergoing noncardiac procedures, and during heart surgery to evaluate the effects of surgical intervention to the heart, such as bypass surgery or valve repair or replacement.
