The action potential is a sudden positive shift in the cardiomyocyte's cellular membrane potential, termed depolarization. Depolarization not only initiates contraction within the affected cardiomyocyte (Described in Cardiac Excitation-Contraction Coupling), but also initiates depolarization of adjacent cardiomyocytes.
Polar Coordinates The coordinate system which depicts the points from the pole to the certain distance at a particular angle is known as âpolar coordinatesâ. The positive horizontal axis in which that particular angle rotates is named as âpolar axisâ.
Find the polar coordinates of the point N. ! 1,4# $ %& ' (2. Find the polar coordinates of the point on the line where ! =#2. ! 2,2# $ %& ' (3. Sketch the line. converting polar functions to rectangular and vice versa Some graphs are more easily written in polar form than rectangular form, r =! e  .
