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.
Transesophageal echocardiography (TEE) is a valuable diagnostic tool that is used routinely to diagnose endocarditis (also called infective endocarditis (IE), endocarditis is an inflammation of the inner lining of the heart)and to evaluate the heart valves and heart function during open heart surgery.
