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.
